A CMOS 5GHz RF transceiver for wireless HDTV distribution

Abstract

A multiple-in multiple-out (MIMO), 5 GHz RF transceiver for wireless HDTV distribution is built with 0.18 mum 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 35 dB image rejection without any on chip calibration. The measurement shows 6 dB typical receiver noise figure and better than 33 dB transmitter EVM at -5 dBm output power.
