Introduction

The MICRF230 is a 400MHz to 450MHz superheterodyne, 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 MICRF230 is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications.
