A 26 GHz Doherty power amplifier MMIC and a fully integrated 2×2 PA array based on the DPA are presented in this paper. The Doherty power amplifier using 0.15μm GaN HEMT technology, achieves maximum small signal gain of 13.6 dB and saturated output power of over 32 dBm in 24–28 GHz, with peak PAE of 21.7%, and 6 dB back-off PAE of 20% at 26 GHz.

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

Power Electronics applications have long employed switching techniques including pulse-width and pulse-density modulation. Because semiconductor technology is growing so quickly, blocks in the radio architecture may benefit from similar strategies. The implementation of a class-D power amplifier for radiofrequency applications in low-GHz frequency ...
