General Description
The MLX71120 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. It is also well-suited for narrow-band applications according to
the ARIB STD-T67 standard in the frequency range 426MHz to 470MHz.
The receiverâs extended temperature and supply voltage ranges make the device a perfect fit for automotive
or similar applications where harsh environmental conditions are expected.
