摘要
结合射频数字预失真技术和Doherty技术提出了一种WCDMA线性化功率放大器的设计方案。通过计算机辅助设计和ADS仿真分析,功率放大器在输出35瓦(45.4dBm)的情况下,ACLR达到-55dBc。
A design of linearized WCDMA power amplifier is introduced in this paper, combining RF DPD and Doherty techniques. By the help of computer aided design and ADS software simulation, it presents that when power amplifier outputs 35W, ACLR has reached - 55 dBcs.
