The MLX71120 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 general purpose applica-tions 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 * fit for automotive or similar applications where harsh environmental conditions are expected.
