The Micrel Inc. MICRF220 is a super-heterodyne, image-reject RF receiver designed for applications requiring low-cost, low-power operation. It covers a frequency range of 300MHz to 450MHz and operates from a supply voltage of 3.0V to 3.6V.
Key electrical specifications include a sensitivity of -110dBm at 1kbps with 0.1% BER, supporting bit rates up to 20kbps. It features a 25dB image-reject mixer and a 60dB analog RSSI output range. The device typically consumes 4.3mA at 315MHz and 6.0mA at 433.92MHz, with a shutdown mode reducing current to 0.1μA.
Packaged in a 16-pin QSOP, the MICRF220 operates within a temperature range of -40°C to +105°C. It includes integrated squelch features to reduce activity on the data output pin until valid bits are detected, enhancing overall receiver sensitivity. This makes it suitable for applications such as Remote Keyless Entry (RKE) and Tire Pressure Monitoring Systems (TPMS).
