Abstract :
A push-pull Doherty Power Amplifier (DPA) is proposed that uses a wideband power combiner BALUN, which is capable to provide the optimum fundamental and 2nd harmonic loading conditions over a large operating bandwidth to the active devices. A 700W DPA demonstrator using these techniques provides high average efficiency (> 40%) for a 7.5dB PAR DVB-T signal over a 37% relative RF-bandwidth.
