General Description
The MLX71121 is a multi-band, single-channel RF receiver based on a double-conversion super-heterodyne
architecture. It can receive FSK and ASK modulated signals. The IC is designed for general purpose
applications for example in the European bands at 433MHz and 868MHz or for similar applications 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.
