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 800 MHz to 930 MHz. The rfRXD0420 and rfRXD0920 share a common architecture. They can be configured for Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), or FM modulation. The rfRXD0420/0920 are compatible with rfPIC™ and rfHCS series of RF transmitters.
