MICRF229 Overview
The MICRF229 is a 400MHz to 450MHz superheterodyne, image-reject, RF receiver with automatic gain control, ASK/OOK demodulator, and analog RSSI output. It only requires a crystal and a minimum number of external ponents to implement. The MICRF229 is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications.
