摘要

采用低成本46-GHz-f/sub - T/硅双极技术实现了用于IEEE 802.11a和HIPERLAN2无线局域网的5 ghz发射机前端。该发射机包括一个数字控制的db线性变增益上转换器和一个三级线性功率放大器。在3v电源电压下，前端输出为23.5 dbm，压缩点为1db，最大功率增益为35db，动态范围为30db。dB-线性增益误差小于/spl plusmn/0.8 dB。发射机能够符合标准的严格误差矢量幅度要求，最高可达19 dbm输出功率水平。

A 5-GHz silicon bipolar transmitter front-end for wireless LAN applications

A 5-GHz transmitter front-end for IEEE 802.11a and HIPERLAN2 wireless local area networks was implemented in a low-cost 46-GHz-f/sub T/ silicon bipolar technology. The transmitter includes a digitally controlled linear-in-dB variable-gain up-converter and a three-stage linear power amplifier. At a 3-V supply voltage, the front-end exhibits a 23.5-dBm output 1-dB compression point, 35-dB maximum power gain, and 30-dB dynamic range. The dB-linear gain error is lower than /spl plusmn/0.8 dB. The transmitter is able to comply with the stringent error vector magnitude requirement of the standard up to a 19-dBm output power level.
