The rfRXD0420/0920 are low cost, compact singlefrequency short-range radio receivers requiring only aminimum number of external components for acomplete receiver system. The rfRXD0420 covers thereceive frequency range of 300 MHz to 450 MHz andthe rfRXD0920 covers 800 MHz to 930 MHz. TherfRXD0420 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.
