Abstract

After providing an introduction to active antenna systems (AAS) for cellular infrastructure, this paper presents power amplifier (PA) modules based on a balanced configuration of 2-8 fully integrated Doherty MMIC PAs. To our knowledge for the first time, a module with four Doherty MMIC PAs in a balanced configuration has been fabricated and tested. For a 10 MHz wide LTE downlink signal at 751 MHz, average and peak output power levels were 37.8 dBm and 45.0 dBm, respectively, with ACPR ≤-48.5 dBc. Overall PAE was 34 %.

基于四个完全集成的Doherty PA mmic的45 dBm平衡功率放大器模块是蜂窝基础设施有源天线系统的可扩展解决方案

在介绍了用于蜂窝基础设施的有源天线系统(AAS)之后，本文介绍了基于2-8个完全集成Doherty MMIC PAs的平衡配置的功率放大器(PA)模块。据我们所知，在平衡配置下，一个具有四个Doherty MMIC PAs的模块已经被制造和测试。对于751 MHz的10 MHz宽LTE下行信号，平均输出功率为37.8 dBm，峰值输出功率为45.0 dBm, ACPR≤-48.5 dBc。总体PAE为34%。
