Description

The rfRXD0920 is a low cost, compact single frequency short-range radio receiver requiring only a minimum number of external components for a complete receiver system. The covers 800 MHz to 930 MHz. They share a common architecture. They can be configured for Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), or FM modulation. The rfRXD0920 is compatible with rfPIC? and rfHCS series of RF transmitters.
