| Abstract: |
| As the core equipment of millimeter-wave(MMW) system TX channels, solid-state po
wer ampl
ifier(PA) has been gradually replacing traditional Traveling-wave Tube(TWT) PA
due to its superiorities i
ncluding high reliability. This paper introduces the domestic and foreign devel
opment of MMW solid-state PA researches. Aiming at some key techniques such as p
ower-combining, solid-state PA linearization etc., it analyses each feature of d
istinct technical approaches and summarizes some practical technical methods. Th
e key directions of the future work are also investigated. |
