MAX2851ITK+ by Analog Devices

5GHz, 5-Channel MIMO Receiver


The MAX2851 is a single-chip, 5-channel RF receiver IC designed for 5GHz wireless HDMI™ applications. The IC includes all circuitry required to implement the complete 5-channel MIMO RF receiver function and crystal oscillator, providing a fully integrated receive path, VCO, frequency synthesis, and baseband/control interface. It includes a fast-settling sigma-delta RF fractional synthesizer with 76Hz frequency programming step size. The IC also integrates on-chip I/Q amplitude and phase-error calibration circuits. The receiver includes both an in-channel RSSI and also an RF RSSI. On-chip monolithic filters are included for receiver I/Q baseband signal channel selection, for supporting both 20MHz and 40MHz RF channels. The baseband filtering and Rx signal paths are optimized to meet stringent WHDI requirements. The downconverter local oscillator is coherent among all the receiver channels. The reverse-link control channel uses an on-chip 5GHz OFDM transmitter. It shares the RF synthesizer and LO generation circuit with the MIMO receivers. Dynamic on/off control of the external PA is implemented with programmable precision voltage. An analog mux routes external PA power-detect voltage to the RSSI pin. The MIMO receiver chip is housed in a small 68-pin TQFN leadless plastic package with exposed paddle.
