摘要

采用46 ghz -f/sub - T/纯硅双极技术实现了一个5 ghz无线电收发器前端芯片组,包括一个图像抑制下转换器和一个db线性可变增益上转换器。下变频器的噪声系数为4db,功率增益为22db,输入压缩点为- 20dbm。它还具有高于60 db的图像抑制比。上变频器可实现6dbm的1db输出压缩点,13db功率增益,提供30db动态范围内的db内线性增益特性。总体电流消耗为68 ma,来自3 v电源电压。

A 5-GHz silicon bipolar radio transceiver front-end
A 5-GHz radio transceiver front-end chipset, including an image-reject down-converter and a dB-linear variable-gain up-converter, was implemented in a 46-GHz-f/sub T/ pure silicon bipolar technology. The down-converter has a 4-dB noise figure, a 22-dB power gain and a 1-dB input compression point of -20 dBm. It also exhibits an image rejection ratio higher than 60-dB. The up-converter achieves a 1-dB output compression point of 6-dBm, a 13-dB power gain, providing a linear-in-dB gain characteristic with a dynamic range of 30-dB. The overall current consumption is 68-mA from a 3-V supply voltage.
