A 45 dBm balanced power amplifier module based on four fully integrated Doherty PA MMICs A scalable solution for cellular infrastructure active antenna systems

2012 42nd European Microwave Conference, 2012
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
