MICRF229 400MHz to 450MHz ASK/OOK Receiver with Auto-Poll and RSSI General Description The MICRF229 is a 400MHz 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 MICRF229 is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications. The MICRF229 achieves 112dBm sensitivity at a bit rate of 1kbps with 1% BER. Eight demodulator filter bandwidths are selectable in binary steps from 1625Hz to 34kHz at 433.92MHz, allowing the device to support bit rates up to 20kbps. The device operates from a supply voltage of 3.5V to 5.5V, and typically consumes 6.0mA at 433.92MHz.
