摘要

提出了一种用于1.8 GHz频段EDGE极性发射机的全集成CMOS射频功率放大器。采用0.18 μ m CMOS工艺实现。当频率在1.71 ~ 1.91 GHz范围内变化时，输出功率为33.4 ~ 33.5 dBm，功率增加效率为39% ~ 41%。当电源电压从0.8 V变化到3.3 V时，动态范围增加了12 dB，满足EDGE动态范围37 dB的要求。

A High Dynamic Range CMOS RF Power Amplifier with a Switchable Transformer for Polar Transmitters

A fully integrated CMOS RF power amplifier for a 1.8 GHz band EDGE polar transmitter is presented. It is implemented with 0.18-mum CMOS process. The output power is 33.4 ~ 33.5 dBm and the power added efficiency is 39 ~ 41 percent when the frequency varies from 1.71 to 1.91 GHz. The dynamic range is increased by 12 dB with the use of the proposed switchable transformer, which meets the EDGE dynamic range requirement of 37 dB when the supply voltage changes from 0.8 to 3.3 V.
