The MLX71121 is a multi-band, single-channel RF receiver based on a double-conversion *-heterodyne 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 433MHz and 868MHz or for the use in North America or Asia, e.g. at 315MHz, 447MHz or 915MHz.
The receiver’s extended temperature and supply voltage ranges make the device a * fit for automotive or similar applications where harsh environmental conditions are expected.
