摘要

基于0.18 μm SiGe BiCMOS工艺，实现了一个8~14 GHz的宽带功率放大器芯片.通过采用增益分布技术有效地拓展了放大器的工作带宽而又不会显著恶化增益；利用基于变压器的功率合成技术，显著地提高了放大器的输出功率.测试结果表明，放大器获得了27 dB的峰值增益，6 GHz的3dB带宽，其中带宽比为54.5%.在3dB范围内，放大器获得了17.5~20.5 dBm的饱和输出功率，以及12~18%的附加效率.包含压焊盘在内的芯片约为1.0 mm.

Abstract

An 8-16 GHz wideband power amplifier was implemented based on the 0.18 μm SiGe BiCMOS process. By using the peak-gain distribution technique

the bandwidth of the amplifier is expanded effectively without significantly deteriorating the available gain. The high output power is achieved by combining the output power of two PA cells using a transformer. The measured results show that the amplifier features a peak gain of 27 dB

and a 3-dB bandwidth of 6 GHz with a bandwidth ratio 54.5%. At the 3-dB bandwidth frequency ranges

the amplifier achieves a saturation output power from 17.5~20.5 dBm

while the power added efficiency is 12-18%. The whole chip including all testing pads is 1.0 mm.
