MICRF220AYQS Datasheet PDF - Micrel

●General Description 

●The MICRF220 is a 300MHz to 450MHz super heterodyne, image-reject, RF receiver with automatic gain control, ASK/OOK demodulator, analog RSSI output, and integrated squelch features. It only requires a crystal and a minimum number of external components to implement. The MICRF220 is ideal for low-cost, low power, RKE, TPMS, and remote actuation applications.
