TDA5201 - ASK Receiver 315-345MHz -113dBm | Infineon
MPN： TDA5201 ✓ 啟用中TDA5201 概覽
An ASK (Amplitude Shift Keying) receiver is a type of RF receiver that demodulates information encoded in the amplitude of a carrier wave. Within the wireless hierarchy, it belongs to the category of short-range RF receivers used in sub-GHz unlicensed-band radio links, sitting between the antenna front end and the baseband decoder in a typical remote-control or telemetry system. Single-conversion superheterodyne receivers such as the TDA5201 down-convert the RF signal to an intermediate frequency in one mixing stage, offering a good balance of sensitivity, selectivity, and low external component count.
Key features include a high level of integration requiring only a few external components, very low power consumption suitable for battery-operated remote controls, ASK demodulation with received signal strength indication, and operation across the 315 MHz to 345 MHz receive range per the DigiKey product listing. The integrated low-noise amplifier, mixer, IF limiter, and demodulator reduce bill-of-material cost and board area.
Technically, the receiver chain comprises an LNA feeding a single-conversion mixer, a limiting IF amplifier, and an ASK demodulator with data slicer, allowing direct interfacing to standard microcontrollers. The -113 dBm sensitivity supports link budgets of several hundred meters in open field with typical 315 MHz remote-control transmitters.
Typical applications include 315 MHz keyless-entry receivers, garage-door openers, wireless alarm and security systems, and low-cost home-automation remote controls.
Design consideration: crystal and IF resonator placement on the PCB strongly influences selectivity and spurious response; follow the Infineon reference layout for optimum performance.

典型應用
TDA5201 適用於 6 應用s: 315 MHz Keyless Entry Receivers, Wireless Security and Alarm Systems, Garage Door Openers, Home Automation Remote Controls, Wireless Doorbell and Telemetry Receivers, SRD 345 MHz Remote Sensor Networks.
315 MHz Keyless Entry Receivers
The TDA5201 natively covers the 315 MHz North American ISM band with -113 dBm sensitivity, enabling keyless-entry base stations to decode remote fob transmissions at ranges of hundreds of meters in open field. Its single-conversion architecture integrates the LNA, mixer, IF limiter, and ASK demodulator, so the base station PCB needs only a crystal, IF resonator, and a few discretes around the PG-TSSOP-28 package. The very low power consumption allows the receiver to remain armed continuously in mains-backed or battery-assisted door modules. Data output interfaces directly to a microcontroller decoder such as a rolling-code IC, and the high sensitivity compensates for the -6 to -10 dB gain penalty of compact loop or PCB trace antennas typical of automotive and garage-door receiver housings.

Wireless Security and Alarm Systems
Alarm panels and wireless door/window sensor receivers benefit from the TDA5201's -113 dBm sensitivity and 315/345 MHz coverage, which maximize transmission reliability from battery-powered PIR and contact sensors. The single-chip ASK receiver integrates the full down-conversion and demodulation chain, reducing the RF section to the TSSOP-28 IC plus matching network, crystal, and IF resonator, keeping receiver module cost low for high-volume security manufacturing. Very low power consumption permits wall-mounted panels to operate in standby with minimal load on backup batteries, an important consideration in UL-style alarm designs. The stable superheterodyne selectivity rejects nearby 315 MHz interference from garage openers and weather stations, reducing false alarms compared with simpler regenerative or super-regenerative receiver architectures.

Garage Door Openers
Garage-door opener receiver modules operating at 315 MHz or 345 MHz are a classic fit for the TDA5201: the part was designed exactly for this class of low-cost, high-volume remote-control link. The -113 dBm sensitivity ensures reliable actuation even from vehicles parked at the driveway edge, while the single-conversion architecture keeps the bill of materials to a handful of external components on the opener control PCB. The TSSOP-28 surface-mount package suits automated assembly of the high-volume opener boards, and the very low power draw keeps standby consumption negligible in always-powered units. Its ASK demodulator output connects directly to the rolling-code decoder in the opener MCU, and family companion transmitters (TDA5100/TDA5101) cover the remote fob side of the link.

Home Automation Remote Controls
Low-cost home-automation receivers (switch modules, plug-in dimmer receivers) in the 310-350 MHz SRD band use the TDA5201 as a compact, integrated ASK front end. High integration means the RF stage occupies minimal PCB area next to the triac or relay driver, and the very low power consumption matters in switch modules that run hot in confined wall boxes. The -113 dBm sensitivity allows remote wall switches to command receivers through multiple interior walls, where each wall typically costs 3-10 dB of link budget. The receiver's data slicer output feeds standard encoder/decoder ICs or general-purpose MCUs running software decoding of protocols such as typical 315 MHz OOK remote formats, making the TDA5201 a flexible, low-BOM-cost choice for consumer automation platforms.

Wireless Doorbell and Telemetry Receivers
Wireless doorbells and simple telemetry receivers at 315/345 MHz exploit the TDA5201's low external-component count and -113 dBm sensitivity to deliver long range from a coin-cell or alkaline push-button transmitter. In the doorbell receiver, the ASK demodulator output drives the chime logic MCU directly, and the receiver can duty-cycle its supply for further power savings in battery-only door chimes. For low-rate telemetry such as mailbox sensors, weather-station add-ons, and pool alarms, the single-conversion receiver provides stable selectivity against the crowded 315 MHz ISM band. The PG-TSSOP-28 package supports compact, low-cost two-layer PCB designs, keeping per-unit cost low enough for disposable-consumer price points typical of these product categories.

SRD 345 MHz Remote Sensor Networks
Short-range-device sensor networks in the 345 MHz band, common in North American security and metering accessories, use the TDA5201 as the receiver node front end. The 310-350 MHz coverage spans all standard SRD allocations in the band, so one receiver design serves multiple sensor product variants. With -113 dBm sensitivity and single-conversion selectivity, star-network sensors achieve robust links at low transmit power, extending coin-cell transmitter life. The integrated RSSI-type ASK demodulation path lets the host MCU evaluate link quality during network commissioning, and the very low power consumption suits receivers that poll periodically under battery power. Minimal external components (crystal, IF resonator, matching network) around the TSSOP-28 keep node cost and board area small.

設計說明
The TDA5201 integrates LNA, mixer, IF limiter, and ASK demodulator, so remaining external components (crystal, IF resonator, antenna matching network, decoupling) determine system performance. Place the crystal and IF resonator as close as possible to the PG-TSSOP-28 pins with short, direct traces. Keep the RF input path (antenna to LNA input) away from the demodulator data output to avoid self-demodulation and spurious reception. Follow the Infineon datasheet reference layout for optimum -113 dBm sensitivity.
The TDA5201 is specified for very low power consumption, which benefits battery-powered receivers. Decouple the supply pin with a 100 nF ceramic capacitor directly at the pin plus a bulk 1-10 uF capacitor per board, since RF receivers are sensitive to supply ripple which can appear as AM noise at the data output. Estimated: even a 50 mVpp 100 Hz supply ripple can degrade effective sensitivity in high-gain ASK chains, so clean LDO-supplied rails are strongly preferred over shared switching rails.
The TDA5201 is sourced through Rochester Electronics (licensed aftermarket) via the DigiKey Marketplace, so verify date codes and authenticity documentation when purchasing in volume. If a new design requires a forward-production part, migrate to the newer Infineon TDA5235XUMA1 or TDA5240 family members - but plan for a PCB respin, since register configuration and pin functions differ from the classic TDA5201 despite the shared family TSSOP-28 footprint.
合規資訊
