Overview

MICRF219A 300MHz to 450MHz ASK/OOK Receiver with Auto-Poll, and RSSI General Description The MICRF219A is a 300MHz 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 components to implement.
The MICRF219A is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications.
The MICRF219A 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 operates from a supply voltage...
