General Description

The MLX71121 is a multi-band, single-channel/dual-channel RF receiver based on a double-conversion

super-heterodyne architecture. It can receive FSK and ASK modulated signals. The IC is designed for gen-

eral purpose applications for example in the European bands at 433MHz and 868MHz or for similar applica-

tions in North America or Asia, e.g. at 315MHz or 915MHz.

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.
