Multi-band single-channel receiver FSK/FM/ASK - 300 to 930 MHz (internal IF filter)

MLX71121

The MLX71121 is a multi-band, single-channel RF receiver based on a double-conversion superheterodyne architecture. It can receive FSK and ASK modulated signals.

The IC is designed for a variety of applications, for example in the European bands at 433 MHz and 868 MHz or for the use in North America or Asia, for example at 315 MHz, 447 MHz or 915 MHz.

The receiver’s extended temperature and supply voltage ranges make the device a perfect fit for automotive or similar applications where harsh environmental conditions are expected.
