The Texas Instruments CC1125RHBR is a fully integrated single-chip ultra-high-performance narrowband RF transceiver covering 164 MHz to 192 MHz, 274 MHz to 320 MHz, 410 MHz to 480 MHz, and 820 MHz to 960 MHz ISM/SRD bands, delivering up to 16 dBm output power at data rates up to 200 kbps, housed in a 32-pin VFQFN package with exposed pad. An RF transceiver is an integrated circuit that combines a transmitter and a receiver sharing a single antenna interface and frequency synthesis path, forming the core of any half-duplex wireless link. Within the power management and connectivity hierarchy, the CC1125 belongs to the sub-1 GHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) radio family, sitting above simple RF front-end modules because it integrates the complete physical layer. Key differentiating features include fully integrated IF filtering that eliminates costly external SAW filters, a high-performance narrowband architecture optimized for channels as tight as 12.5 kHz, very low-power and low-voltage operation, and an on-chip packet engine with CRC and address handling that offloads the host MCU. According to the TI product page, the device is designed for cost-effective wireless systems requiring long range and high link reliability. Technically, the CC1125 uses a zero-IF receive architecture with integrated channel filters, a fractional-N synthesizer, and a programmable power amplifier reaching +16 dBm. The narrowband design maximizes spectral efficiency and interference rejection, which is the primary reason engineers select it over wideband FSK parts like the CC1101 family for professional telemetry and metering systems. Typical applications include smart metering, industrial telemetry and SCADA links, professional wireless audio and intercom systems, alarm and security networks, and narrowband IoT backhaul, where the 200 kbps data rate and 16 dBm output extend link budgets well beyond wideband alternatives. Design considerations: the exposed pad is the primary ground return and must be soldered to a solid ground plane with thermal vias, and RF matching networks must be band-specific per TI reference designs.

CC113LRGPR - Sub-1GHz RF Receiver, -116dBm | Texas Instruments
The Texas Instruments CC113LRGPR is a cost-optimized Value Line sub-1 GHz RF receiver supporting FSK, GFSK, and OOK modulation across 315 MHz, 433 MHz, 868 MHz, and 915 MHz bands, with -116 dBm link sensitivity and up to 600 kbps data rate, housed in a 20-pin QFN (4x4 mm) surface-mount package with exposed pad. A sub-1 GHz RF receiver is a radio-frequency integrated circuit that demodulates low-frequency wireless signals, sitting within the broader hierarchy of wireless connectivity ICs: RF receiver -> RF transceiver family -> RF & wireless semiconductors. Sub-1 GHz radio offers longer range and lower power than 2.4 GHz alternatives such as Bluetooth or Zigbee, which is why it dominates metering, alarm, and telemetry systems. Key features of the CC113L include a highly configurable baseband demodulator, -116 dBm sensitivity at low data rates for maximum link budget, 600 kbps maximum data rate for fast telemetry, and a low 17.1 mA receive current for battery-powered designs. The receiver covers three frequency ranges - 300-348 MHz, 387-464 MHz, and 779-928 MHz - allowing one design to serve regional ISM bands worldwide. According to Texas Instruments, the CC113L circuit is based on the popular CC1101 RF transceiver and its RF performance characteristics are identical; the silicon is paired with the CC115L transmitter to create a low-cost split Tx/Rx RF link. Because the architecture is inherited from CC1101, register-level configuration tools, SmartRF Studio support, and reference designs port directly, reducing development risk. The integrated baseband supports packet handling, RSSI measurement, and carrier-sense functions via a serial configuration interface. Typical applications include wireless alarm and security receivers, smart metering gateways, industrial telemetry, keyless entry receivers, and low-power sensor polling systems. Pairing the CC113L receiver with the CC115L transmitter yields a cost-optimized bidirectional link without paying transceiver prices on both ends. Design consideration: the CC113L is receiver-only, so systems requiring bidirectional communication must budget for a separate transmitter or select a CC1101/CC110L transceiver instead. Antenna matching and RBIAS resistor placement follow the CC1101 reference designs.

A sub-1 GHz RF receiver is a radio-frequency IC that demodulates low-frequency wireless signals such as FSK, GFSK, and OOK, converting modulated RF energy into digital baseband data. Within the system hierarchy, it belongs to the RF receiver category of wireless connectivity ICs, complementing transceivers and transmitters in low-power wireless links for sensor networks, telemetry, and industrial control. Because receive-only links do not need a transmitter chain, receiver-only parts reduce system cost and power consumption in downlink-only or asymmetric architectures. Key features of the CC113L include a highly configurable baseband demodulator supporting packet handling, a receive sensitivity of -116 dBm at low data rates for long-range links, a flexible frequency synthesizer supporting multi-band operation, and digital RSSI and LQI outputs for link quality assessment. The CC113L is based on the popular CC1101 RF transceiver, and according to Texas Instruments, RF performance characteristics are identical, which eases migration from existing CC1101-based receiver designs. The device integrates a low-IF superheterodyne receiver architecture with configurable channel filter bandwidths, enabling robust operation in congested ISM bands. Combined with the CC115L Value Line transmitter, the CC113L enables a low-cost, split-architecture RF link where the transmit side and receive side are optimized independently. Typical applications include 433 MHz and 868/915 MHz wireless sensor networks, smart metering downlinks, industrial telemetry and SCADA nodes, home automation receivers, and low-power alarm and security receivers. Its low active receive current and flexible sleep/wakeup strobe commands make it well suited for battery-powered nodes. A key design consideration is RF matching: the differential RF input requires a balanced-to-unbalanced (balun) network plus antenna matching components for optimal sensitivity, and crystal accuracy affects frequency error at the band edges.

Technically, the device merges TI's proven CC1101 transceiver front end with the MSP430 bus architecture, so RF register configuration, packet handling, and application code all execute on one CPU. This removes the SPI timing race conditions and firmware coordination overhead typical of two-chip designs. Flash memory is in-system programmable, supporting field firmware and RF-parameter updates. Typical applications include sub-1 GHz wireless sensor networks, AMR/utility metering, home and building automation, alarm and security systems, and industrial monitoring nodes where long range, low duty cycle, and multi-year battery life dominate the design. Design-wise, RF layout on the RGZ-48 exposed-pad package demands a solid ground plane, short matching-network traces, and careful antenna placement; the exposed pad must be soldered to ground for both thermal and RF performance.

CC430F5145IRGZT - Sub-1GHz RF SoC, 16kB Flash | Texas Instruments
The Texas Instruments CC430F5145IRGZT is a 16-bit ultra-low-power wireless microcontroller system-on-chip (SoC) combining an MSP430 CPUXV2 core with an integrated CC1101 sub-1 GHz RF transceiver in a 48-pin VQFN (RGZ) package with exposed pad. It offers 16kB in-system programmable flash, 2kB RAM, a 10-bit ADC, and operates across the 300-348 MHz, 389-464 MHz, and 779-928 MHz ISM/SRD bands. A wireless MCU, or RF SoC, integrates a general-purpose microcontroller and a radio transceiver on a single die, collapsing the traditional two-chip MCU-plus-transceiver architecture into one package. This reduces bill-of-materials count, board area, and inter-chip interface complexity, sitting within the broader hierarchy of microcontrollers and RF transceiver ICs in the power management and connectivity domain. Key features include the CC1101-format radio supporting flexible modulation (2-FSK, GFSK, MSK, OOK, ASK), programmable data rates, and packet handling in hardware; ultra-low-power operation typical of the MSP430 family with multiple low-power modes; two 16-bit timers; and a high-performance 10-bit ADC with six external inputs plus internal temperature and battery sensors. Technically, the RF core shares a single crystal with the digital domain, and the MSP430 CPUXV2 delivers efficient 16-bit computation with fast wake-up from low-power modes, making the device well suited to battery-powered duty-cycled networks. The unified architecture simplifies RF-to-MCU data flow through dedicated radio register interfaces. Typical applications include wireless sensor networks, smart metering, building automation, alarm and security systems, and industrial telemetry, where multi-year battery life and robust sub-1 GHz link budgets matter more than raw throughput. Design consideration: RF layout of the VQFN-48 exposed pad requires careful impedance matching to the antenna per TI reference designs (e.g., DN023 style matching networks), and developers should budget flash/RAM headroom since 16kB/2kB is the smaller end of the CC430 memory range.
CC660D-LS - 3GPP NTN Satellite IoT Module LCC+LGA | Quectel
The Quectel CC660D-LS is a 3GPP NTN (Non-Terrestrial Network) satellite communication module that supports 3GPP Release-17 IoT-NTN connectivity in L-band (B255) and S-band (B256/B23), housed in a compact LCC + LGA surface-mount package measuring 17.7 mm × 15.8 mm × 2.0 mm. It delivers two-way data communication plus SMS SOS functionality, enabling direct device-to-satellite links for IoT deployments that previously required terrestrial cellular coverage. A satellite IoT module is a self-contained wireless subsystem that integrates a baseband transceiver, RF front-end, power management and host interface into a single certified PCB. Within the broader electronics taxonomy it sits as: IoT module -> wireless module -> RF module -> electronic component. Direct-to-satellite modules like the CC660D-LS remove the dependency on terrestrial base stations, extending connectivity to maritime, agricultural, asset-tracking and emergency-response use cases where cellular coverage is absent. Key features include IoT-NTN Rel-17 protocol support over L-band (B255) and S-band (B256/B23), GNSS location reporting, integrated IP/UDP/TCP stacks, and an ultra-compact 17.7 × 15.8 × 2.0 mm LCC + LGA footprint suitable for SMT mass production. The module is designed for durable, rugged designs and is positioned for size-sensitive end products. Technically, the CC660D-LS pairs a 3GPP Rel-17 IoT-NTN baseband with multi-band RF front-end and integrated GNSS for location reporting. Because it operates exclusively through non-terrestrial network satellites, link budget, antenna gain and sky-view geometry become dominant design considerations; the module is intended to be paired with an active or passive NTN-tuned antenna. Typical applications include global asset tracking, maritime and fishery monitoring, agricultural sensor telemetry, SCADA fallback for remote industrial sites, and emergency SOS wearables. It is generally used together with a GNSS module, since CC660D-LS relies on GNSS to update location before transmitting via satellite. When designing with this module, ensure the host platform supplies a stable 3.3 V–4.3 V supply, that the antenna is tuned for the chosen NTN band, and that the SIM interface matches the operator's satellite SIM provisioning (which differs from terrestrial SIMs). This page synthesizes distributor availability, parametric positioning versus competing IoT-NTN modules, and practical integration notes not found in the manufacturer datasheet alone.
CI522 - 13.56MHz ISO14443A RFID Reader IC QFN-16 | Nanjing Zhongke
The Nanjing Zhongke Microelectronics CI522 is a 13.56 MHz contactless reader/writer IC supporting ISO/IEC 14443 A communication at up to 848 Kbit/s, housed in a 16-pin QFN-EP (3x3 mm) package. It integrates a built-in antenna driver, hardware data verification (CRC/parity), low-power wake-up, and an SPI host interface operating from 2.3 V to 4 V supply, targeting contactless reader front-ends in access control, smart-locker, and NFC token applications. What is an RFID reader IC? An RFID reader IC (radio-frequency identification reader IC) is a contactless front-end transceiver that powers a passive transponder (tag or card) over a magnetic field at 13.56 MHz, exchanges modulated data using a defined air protocol such as ISO/IEC 14443 A/B or ISO 15693, and presents a digital interface (SPI, UART, I2C) to a host microcontroller. It belongs to the broader hierarchy: RFID reader IC -> 13.56 MHz NFC front-end -> contactless communication IC -> wireless/RF semiconductor -> semiconductor device. The CI522 implements the type-A sub-protocol of ISO/IEC 14443, which is the most widely deployed air interface for contactless smartcards (MIFARE Classic, MIFARE Ultralight, NTAG) and is the de-facto standard for transit fare cards and access badges. Key features include an integrated transmit-side antenna driver capable of driving a printed or wound loop directly without an external power amplifier, on-chip CRC and parity verification to offload the host MCU, a configurable low-power wake-up mode that periodically polls the RF field to extend battery life in coin-cell designs, and SPI communication up to 10 Mbit/s. The 3x3 mm QFN-EP package with exposed pad keeps the PCB footprint compact while the thermal pad provides a low-impedance ground reference that is essential for stable RF performance. Technically, the CI522 combines a 13.56 MHz resonant bridge with modulation/demodulation, anti-collision logic compliant with ISO 14443-3 type A, and a small command engine that handles REQA, SELECT, AUTH, READ, WRITE, and HALT transactions internally. Its low-power wake-up and short command latency enable wake-on-proximity designs where the host sleeps until a card is detected. Typical applications include access control readers, RFID card writers/programmers for MIFARE Classic 1K/4K and Ultralight tags, smart-locker and shared-mobility kiosks, NFC payment terminals (Type A tags), and battery-powered handheld readers. In each case the CI522 handles the RF and protocol layers so that the host MCU can focus on application logic. A key design consideration is the antenna matching network - the loop inductance, tuning capacitor, and EMC filter values must be chosen for the specific coil geometry and target card distance; using the recommended reference design from the manufacturer datasheet is the safest path.

It functions as a highly flexible 13.56 MHz contactless reader frontend that supports multiple NFC and RFID standards, offering an extended temperature range and pin-to-pin compatibility across the CLRC663 plus family. An NFC frontend, also called an NFC reader IC or contactless reader frontend, is a radio-frequency integrated circuit that generates the 13.56 MHz carrier, modulates and demodulates the contactless signal, and communicates with a host microcontroller that runs the higher protocol layers. In the system hierarchy it sits between the antenna matching network and the host MCU, making it a key element of wireless RF ICs for NFC/RFID reader designs. Key features highlighted by NXP include high performance with flexible antenna design options, remarkably low power consumption with Low Power Card Detection (LPCD) support, and multi-protocol operation covering mainstream contactless standards. The CLRC663 plus family provides extended temperature range operation, which widens its use beyond consumer devices into industrial and infrastructure reader equipment. Technically, the device integrates the analog front end: low-noise receivers, programmable gain, transmit drivers for antenna configurations, and a digital host interface controlled via register access. The host microcontroller executes NXP protocol software such as the NFC Reader Library (NFCRDLib), which the NXP community confirms is the standard software stack for CLRC663-family parts. Typical applications include contactless payment and ticketing terminals, access-control readers, industrial handheld scanners, and embedded NFC modules for smart-home and IoT devices that must read tags such as NTAG Type 2A parts. Design consideration: the HNK (HVQFN-32) variant is the standard packaged option; NXP also offers alternative packaging (such as the HNE option), so verify the exact suffix against your supply plan, and note that Mouser currently lists this part as non-stocked with a 30-week lead time. This page synthesizes distributor pricing, drop-in family alternatives, lead-time data, and practical design guidance not consolidated in the manufacturer datasheet.
CMD199 - 26-35 GHz GaAs Driver Amplifier Die | Qorvo
The Qorvo CMD199 is a wideband 26-35 GHz (K/Ka/Q band) balanced driver amplifier MMIC fabricated in GaAs pHEMT technology, delivering 15 dB of gain with a +19.5 dBm output 1 dB compression point and 3.5 dB noise figure at 30 GHz, supplied as an unpackaged die for hybrid and module assembly. A driver amplifier MMIC is a radio-frequency integrated circuit that provides gain and power boosting between a signal source, such as a synthesizer or upconverter, and a final power amplifier stage. Within the RF signal-chain hierarchy, the driver amplifier sits between low-level gain blocks and the high-power PA, and is a key subcategory of RF/microwave amplifiers within power management of the transmit path. Key features include 50 ohm internally matched input and output, which eliminates the need for external DC blocks and RF port matching networks, full passivation for increased reliability and moisture protection, and a balanced topology that improves output match and linearity across the band. Technically, the balanced amplifier architecture uses two 90-degree hybrid-coupled gain stages, which yields good input/output return loss and graceful degradation. GaAs pHEMT process technology supports the high-frequency gain and high linearity needed at Ka and Q band frequencies, where small size and high dynamic range are critical design requirements. Typical applications include military and defense radar and communications systems, space payloads, satellite communications (SATCOM) uplinks, point-to-point microwave backhaul, and test equipment operating in K, Ka, and Q bands, where the die format enables compact module integration. A key design consideration is die-level assembly: the CMD199 requires chip-and-wire bonding or equivalent hybrid assembly with controlled bond-wire inductance, proper RF grounding via via-holes, and thermal design for the dissipating FETs; supplied DC blocking and bias decoupling must follow the manufacturer datasheet recommendations. This page synthesizes distributor availability, pricing context, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
CMD201P5 - DC-20 GHz GaAs Power Amp +27dBm | Qorvo
The Qorvo CMD201P5 is a wideband GaAs MMIC distributed power amplifier operating from DC to 20 GHz, delivering 11 dB of gain with an output 1 dB compression point of +27 dBm and output IP3 of +37 dBm at 10 GHz, housed in a 32-pin QFN (5x5 mm) surface-mount package. A distributed power amplifier is a class of RF/microwave amplifier in which multiple transistor stages are connected via an artificial transmission-line structure, allowing the gain stages to combine their outputs coherently across extremely wide bandwidths. Within the amplifier hierarchy, the CMD201P5 sits as a power-amplifier-stage MMIC, part of the broader family of RF amplifiers within microwave semiconductors. The distributed topology is what enables its DC-to-20 GHz (L, S, C, X, Ku, and K band) frequency coverage, something reactive-matched narrowband designs cannot achieve. Key features include the very wide DC to 20 GHz bandwidth, 11 dB of flat gain, high linearity with +37 dBm output IP3, and a robust +27 dBm P1dB output power rating. The 50-ohm matched input and output design eliminates the need for external RF port matching networks, dramatically simplifying PCB design and reducing board area. Technically, the GaAs MMIC process provides high transition frequency and consistent performance across the multiband range. The distributed amplifier architecture trades some efficiency for bandwidth, making the part especially attractive where a single amplifier must cover multiple legacy and modern frequency bands. Typical applications include electronic warfare and radar transmitters, wideband test and measurement signal chains, and multi-octave communication links covering L through K band. Design consideration: distributed amplifiers draw DC current continuously, so thermal management of the exposed QFN pad with a solid via-fenced ground connection is essential for reliability. This page synthesizes distributor pricing, verified datasheet parameters, and practical design notes not found in the manufacturer datasheet.
CMD243 - 26-35GHz GaAs Driver Amp, 15.5dB Gain | Qorvo
The Qorvo CMD243 is a wideband GaAs MMIC balanced driver amplifier operating from 26 GHz to 35 GHz (K, Ka and Q bands), delivering 15.5 dB of gain, an output 1 dB compression point of +21 dBm, and a noise figure of 4.4 dB at 30 GHz. The CMD243 is supplied as a bare die and is a 50 ohm matched design, which eliminates the need for external DC blocks and RF port matching. A driver amplifier MMIC is a semiconductor device that boosts signal power in an RF transmit chain, sitting between the upconverter or modulator and the final high-power amplifier. Within the power management hierarchy of an RF front end, the driver stage defines system linearity and noise contribution, and the CMD243 addresses the K/Ka/Q band segment used by satellite communications, point-to-point radio, and radar systems. Key features include balanced amplifier architecture for good input and output return loss across the full 26-35 GHz band, +21 dBm P1dB output power that comfortably drives downstream power amplifiers, and a 4.4 dB noise figure that preserves the link budget of the receiver or transmitter chain. The die format enables integration directly into hybrid microwave assemblies, carrier-bonded modules, and hermetic packages. Technically, the CMD243 is fabricated on Qorvo's GaAs pHEMT MMIC process with full passivation, which provides increased reliability and moisture protection compared with unpassivated die. The balanced topology uses 90-degree hybrids to split and recombine two parallel amplifier stages, improving both match stability and tolerance to bond-wire variation in assembly. Typical applications include military and space communications systems, VSAT and satellite uplinks in Ka band, point-to-point microwave backhaul, and test instrumentation requiring broadband gain in the 26-35 GHz range where small size and high linearity are needed. When designing with the CMD243 die, allow sufficient carrier area for bias routing and RF bond wires, and verify thermal dissipation at the +21 dBm output operating point. Exact bias conditions should be confirmed from the manufacturer datasheet before power-up. This page synthesizes distributor availability, drop-in alternative guidance, and practical die-assembly design notes not found in the manufacturer datasheet.
CMD249K5 - DC-20 GHz GaAs Distributed PA | Qorvo | RF Amplifier
The Qorvo CMD249K5 is a wideband GaAs MMIC (Monolithic Microwave Integrated Circuit) distributed power amplifier, part of Qorvo's CMD249 family, designed for RF and microwave applications from DC to 20 GHz. According to the CMD249 family datasheet, the amplifier delivers greater than 12 dB of gain with a corresponding output 1 dB compression point (P1dB) of +30 dBm and an output third-order intercept point (OIP3) of +38 dBm measured at 10 GHz. The device is fabricated in a 50 ohm matched GaAs pHEMT process, which eliminates the need for external RF port matching and simplifies PCB integration. A distributed power amplifier is a specialized RF amplifier topology that uses the absorption principle of transmission lines to achieve broad bandwidth. Unlike traditional reactively-matched amplifiers whose gain rolls off with frequency, distributed amplifiers maintain flat gain over many octaves by absorbing the parasitic gate and drain capacitances of multiple transistor cells into artificial transmission lines. Distributed amplifiers therefore belong to the broader family of broadband RF amplifiers, themselves a subset of microwave ICs within the RF & Wireless product category. The CMD249 family exploits this topology to deliver usable gain from near-DC up to millimeter-wave frequencies in a single, unconditionally-stable stage. Key features of the CMD249 family include full DC to 20 GHz operational bandwidth, +30 dBm output P1dB, +38 dBm OIP3, 12 dB small-signal gain, 50 ohm input/output match eliminating external matching components, full passivation for enhanced reliability, and 100% DC testing on the wafer. The bare-die form factor requires wirebond or flip-chip interconnect to the host PCB. Compared with reactively-matched power amplifiers that cover only a narrow band, the CMD249K5 trades saturated efficiency for bandwidth - it is the part of choice for instrumentation, EW, and multi-band radar where flat response over many octaves matters more than peak PAE. Typical applications include wideband military EW (electronic warfare) jamming and receiver systems, fiber-optic communication drivers, test and measurement instrumentation, multi-band radar, microwave backhaul, and broadband IF/RF gain blocks. The broadband response also makes the CMD249 family suitable as a generic gain block when the system requires a single amplifier covering multiple downstream frequency plans. Designers should note that GaAs distributed amplifiers dissipate substantial DC power (typically several hundred mA at +5 to +8 V supply) and require careful thermal management even at small duty cycles. The bare die format means ESD handling and clean-room assembly practices are mandatory. Designers should also evaluate the trade-off between the CMD249 family's broadband coverage and the higher efficiency of a narrowband power amplifier if the end application only requires a single band.
CMWX1ZZABZ-091 - LoRaWAN Module 868/915MHz | Murata
The Murata CMWX1ZZABZ-091 is a shielded ultra-small LoRaWAN sub-GHz transceiver module operating in the 868 MHz and 915 MHz ISM bands, integrating an STM32L072 Arm Cortex-M0+ microcontroller with 192 KB flash and an SX1276 LoRa transceiver in a 13.5 x 13.8 mm surface-mount land-grid package. A LoRaWAN module is a complete long-range, low-power wide-area network (LPWAN) radio subsystem that combines an RF transceiver, a host microcontroller, antenna matching, crystal references, and a shielded package into a single certified component. In the system hierarchy it sits above a bare transceiver IC: instead of designing RF matching networks and obtaining regional radio certifications yourself, a module such as the Type ABZ drops into a design with only power, ground, UART/SPI/I2C wiring, and an antenna connection required. Key features include support for LoRaWAN Class A and Class C operation, radio-law certification already obtained for major regions (including CE and FCC for 868/915 MHz deployments), and open MCU design support that exposes all STM32L072 peripherals such as ADC, 16-bit timers, LP-UART, I2C, SPI, and USB 2.0 FS. The module can additionally support Sigfox by modifying the firmware, with Sigfox RC1, RC2, and RC4 certification available through the X-CUBE-SFOX package. The Type ABZ architecture benefits from ST's I-CUBE-LRWAN stack and the B-L072Z-LRWAN1 Discovery kit, which embeds the same module, allowing code developed on the Discovery kit to transfer directly to production hardware. Standby-to-active wake-up occurs in approximately 60 microseconds via NRST, WKUP pins, RTC alarm, or RTC wakeup events, supporting strict battery-life budgets in asset-tracking and metering products. Typical applications include smart utility metering, asset trackers, smart-city sensor nodes, agricultural monitoring, and industrial IoT endpoints that require multi-kilometer range and years of battery life. A key design consideration is supply voltage: the module operates at 1.8 V to 3.6 V, so a primary lithium cell or low-dropout regulator should be chosen with adequate headroom for peak transmit current.
