Product Details
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.
