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 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.
