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
