MW7IC2240NBR1 - 4W W-CDMA RF LDMOS Power Amplifier | NXP
MPN: MW7IC2240NBR1 ✗ اختتامِ زندگیMW7IC2240NBR1 جائزہ
A radio-frequency power amplifier (RF PA) is the final active stage of a wireless transmitter chain, responsible for boosting a low-power modulated signal from the transceiver/exciter to a level suitable for the antenna and over-the-air transmission. LDMOS (Laterally Diffused Metal-Oxide Semiconductor) is the dominant technology for sub-6 GHz base-station PAs because it offers high power density, excellent linearity under digital modulation, robust VSWR tolerance, and cost-effective 28-32 V operation. The MW7IC2240NBR1 sits within the hierarchy: RF power amplifier -> power amplifier -> amplifier IC -> RF & wireless -> semiconductor.
The MW7IC2240NBR1 features 50 ohm on-chip matching, which removes the need for external input/output matching networks and simplifies PCB layout. Two quiescent-current bias pins (IDQ1 = 90 mA, IDQ2 = 420 mA) allow independent bias setting for the driver and final stages to optimize gain, linearity, and efficiency. The device is 100% PAR-tested for guaranteed output power capability under W-CDMA-like signals and is characterized with series equivalent large-signal impedance parameters and common-source S-parameters for accurate system-level simulation.

عام استعمالات
MW7IC2240NBR1 کے لیے موزوں ہے 6 ایپلیکیشنs: W-CDMA / UMTS Base Station Power Amplifier, TD-SCDMA Repeater / Small-Cell PA, LTE Band 1 Driver Amplifier, Public-Safety / Private LTE PA, Industrial RF Heating / Plasma Driver (2.1 GHz ISM-adjacent), Avionics / Datalink Transmitter (custom-filtered 2.1 GHz).
W-CDMA / UMTS Base Station Power Amplifier
The MW7IC2240NBR1 is purpose-built for the 2110-2170 MHz UMTS downlink band used in 3G macro and micro base stations. Its 4 W average W-CDMA output with PAR = 7.5 dB matches a small-cell or repeater final-stage power target, while 30 dB typical gain eliminates an external driver stage. The on-chip 50 ohm matching simplifies the PCB layout around the heatsink flange, and the device is 100% PAR-tested to guarantee linear output under real-world digitally modulated drive. Placed after the transceiver/exciter chain with a 28 V rail and input attenuator from PIN, the MW7IC2240NBR1 drives the antenna filter with ACPR-compliant 3GPP W-CDMA spectra in a 3.84 MHz channel bandwidth at +/-5 MHz offset.

TD-SCDMA Repeater / Small-Cell PA
The MW7IC2240NBR1's 2000-2200 MHz usable range covers the 2010-2025 MHz TD-SCDMA uplink and 1900-1920 MHz extended modes when paired with external filtering, making it well-suited for indoor TD-SCDMA repeaters. Its 5:1 input and output VSWR tolerance protects the final stage against antenna mismatch in dense urban deployments. The 28 V operation matches standard small-cell PSU rails, and the multi-stage structure with independent IDQ1 and IDQ2 biasing lets designers trade off gain for efficiency depending on traffic load. Placed between the DPD feedback path and the duplexer with 28 V drain switching, the MW7IC2240NBR1 sustains linear TD-SCDMA output at 4 W average while the bias network adjusts quiescent current to optimize DC consumption at low traffic.

LTE Band 1 Driver Amplifier
LTE Band 1 occupies 2110-2170 MHz, exactly the MW7IC2240NBR1's specified band. At 4 W average with a 7.5 dB LTE PAR profile, the part can serve as the final PA in a small-cell LTE Band 1 radio or as a driver stage for a higher-power macro BTS PA. The LDMOS technology provides the linearity required for OFDM signals with high peak-to-average ratios, and the 28 V supply is the standard rail for LTE base-station infrastructure. Compared with a discrete transistor solution, the MW7IC2240NBR1 reduces the BOM by removing external matching components and a bias sequencer. Placed between the digital pre-distortion feedback path and the higher-power PA chain, the MW7IC2240NBR1 provides 30 dB of gain and 4 W of linear output, with the 28 V drain supplied through an isolated switching converter to keep the PA chain noise off the modulator reference.

Public-Safety / Private LTE PA
The 2110-2170 MHz band is shared with some public-safety and private LTE networks in Region 1, and the MW7IC2240NBR1's W-CDMA / LTE modulation support makes it usable in these deployments. The TO-272 WB-16 over-molded plastic body is smaller and lighter than ceramic-packaged PAs, which matters for vehicle-mounted and portable repeaters. Its 5:1 VSWR tolerance handles the variable antenna conditions of temporary or vehicular installations where the antenna may be obstructed. Placed inside a ruggedized RF module with shock-mounted PCB and weatherproof housing, the MW7IC2240NBR1 delivers 4 W average output to the rooftop antenna while the bias network maintains IDQ2 = 420 mA for thermal stability across the -40 C to +85 C base-station operating range.

Industrial RF Heating / Plasma Driver (2.1 GHz ISM-adjacent)
Although the 2110-2170 MHz band is licensed for cellular use, industrial-scientific-medical (ISM) equipment operating on nearby frequencies can leverage the MW7IC2240NBR1 as a building block when filtered appropriately. The 28 V LDMOS architecture and 4 W average continuous power support plasma generation and RF heating applications that need stable, repeatable 2 GHz-class drive. The 100% PAR-tested output capability ensures that high-CREST-factor loads do not push the device outside its linear region. Placed inside an RF generator with a bandpass cavity filter and directional coupler, the MW7IC2240NBR1 delivers 4 W to the plasma chamber, with the 28 V drain modulated by an external AGC loop that adjusts quiescent current in response to reflected-power feedback.

Avionics / Datalink Transmitter (custom-filtered 2.1 GHz)
Some airborne datalink and telemetry systems operate in custom-filtered windows near the 2.1 GHz cellular band. The MW7IC2240NBR1's small TO-272 WB-16 footprint and 4 W average output are well-matched to compact airborne transmitters where size, weight, and power (SWaP) are critical. Its 5:1 VSWR tolerance handles the variable VSWR presented by an airborne antenna under banking maneuvers. The multi-stage LDMOS design provides the gain needed to drive a single PA from a low-power exciter without an intermediate stage. Placed inside a vibration-isolated RF tray with a low-loss bandpass filter and circulator on the output, the MW7IC2240NBR1 transmits 4 W average to the antenna, with the 28 V rail conditioned by a hold-up capacitor bank to ride out aircraft power transients.

ڈیزائن نوٹس
Estimated: at 4 W Avg. W-CDMA output from 28 V the dissipated power is roughly 11-14 W. The TO-272 WB-16 over-mold body has a typical theta_JC of about 1.5 C/W per NXP LDMOS family curves. Mount the device on a continuous copper ground pour across all GND pins and add a bolted-on aluminum heatsink or cold plate for CW or high-duty operation. Without a heatsink the junction temperature can exceed 150 C at maximum dissipation, triggering thermal shutdown.
Keep the 28 V drain traces wide (>=1 mm per ampere) and decouple at each pin with a 100 nF ceramic + 10 uF electrolytic + 220 uF bulk capacitor stack. Place the gate-bias RC networks (VGG1, VGG2) within 5 mm of their respective pins to prevent low-frequency oscillation. Route RF input and output traces as 50 ohm microstrip on the top layer over a continuous ground plane; the on-chip matching tolerates small PCB parasitic mismatch but a directional coupler on the output is recommended for closed-loop AGC.
Do not exceed 32 V on VDD1 or VDD2 - the LDMOS die is rated 24-32 V only. Sequence gate bias before drain voltage (typical: VGG first, then ramp VDD) to avoid uncontrolled current spikes that can blow the bond wires. The MW7IC2240NBR1 is obsolete as of 2026-10-15; new designs should target the in-production MW7IC2240GNR1 family variant. When biasing, set IDQ1 = 90 mA and IDQ2 = 420 mA at room temperature and re-trim for thermal compensation in production.
