Overview

MICRF220 300MHz to 450MHz, 3.
3V ASK/OOK Receiver with RSSI and Squelch General Description The MICRF220 is a 300MHz 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 MICRF220 is ideal for low-cost, lowpower, RKE, TPMS, and remote actuation applications.
The MICRF220 achieves −110dBm sensitivity at a bit rate of 1kbps with 0.
1% BER.
Four demodulator filter bandwidths are selectable in binary steps from 1625Hz to 13kHz at 433.
92MHz, allowing the device to support bit rates up to 20kbps.
The device ope...
