DEVICE OVERVIEW

The rfRXD0420/0920 are low cost, compact single frequency short-range radio receivers requiring only a minimum number of external components for a complete receiver system. The rfRXD0420 covers the receive frequency range of 300 MHz to 450 MHz and the rfRXD0920 covers 800MHz to 930 MHz.

Features:

• Low cost single conversion superheterodyne receiver architecture

• Compatible with rfPIC™ and rfHCS series of RF transmitters

• Easy interface to PICmicro® microcontroller (MCU) and KEELOQ® decoders

• VCO phase locked to quartz crystal reference:

- Narrow receiver bandwidth

- Maximizes range and interference immunity

• Selectable LNA gain control for improved dynamic range

• Selectable IF bandwidth via external ceramic IF filter

• Received Signal Strength Indicator (RSSI) for signal strength indication (FSK, FM) and ASK demodulation

• FSK/FM quadrature (phase coincidence) detector demodulator

• 32-Lead LQFP package

Applications:

• Wireless remote command and control

• Wireless security systems

• Remote Keyless Entry (RKE)

• Low power telemetry

• Low power FM receiver

• Home automation

• Remote sensing
