A CMOS 5GHz RF transceiver for wireless HDTV distribution

A multiple-in multiple-out (MIMO), 5GHz RF transceiver for wireless HDTV distribution is built with 0.18µm CMOS technology. The transceiver utilizes a direct up transmitter and low-IF receiver architecture. A dual-quadrature direct up conversion mixer is used that achieved better than 35dB image rejection without any on chip calibration. The measurement shows 6dB typical receiver noise figure and better than 33dB transmitter EVM at −5 dBm output power.
