An integrated CMOS high data rate transceiver for video applications
适于视频应用的高数据传输率集成CMOS收发机

This paper presents a 5GHz CMOS Radio Frequency (RF) transceiver built with 0.18mm RF-CMOS technology by using a proprietary protocol, which combines the newer IEEE 802.11n features such as multiple-in multiple-out (MIMO) technology with other wireless technologies to provide high data rate robust real time high definition television (HDTV) distribution within a home environment. The RF frequencies cover from 4.9GHz to 5.9GHz the Industrial, Scientific and Medical (ISM) band. Each RF channel bandwidth is 20MHz. 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 Error Vector Magnitude (EVM) at -3dBm output power.
