Device Overview

Summary

The MICRF219A 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 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 of 3.0V to 3.6V, and typically consumes 4.3mA of supply current at 315MHz and 6.0mA at 433.92MHz.  A shutdown mode reduces supply current to 0.1µA typical.  The squelch feature decreases the activity on the data output pin until valid bits are detected while maintaining overall receiver sensitivity.
