A Highly Efficient Asymmetric Doherty Power with a New Output Combining Circuit
by Junghwan Son, Ildu Kim, Junghwan Moon, Juyeon Lee, Bummam Kim

An asymmetric Doherty Power Amplifier (ADPA) is introduced using a new output combining circuit for easy of implementation with a large matching tolerance. The proposed APDA has been implemented using GaN HEMT devices at 2.6 GHz for WiMAX signal with 5MHz bandwidth and 8.3 dB peak to average power ratio.

Harmonically Tuned Octave Bandwidth 200 W GaN Power Amplifier
by MHD. Tareq Arnous; Khaled Bathich; Sebastian Preis; Georg Boeck

In this paper, the design, implementation, and experimental results of a 200 W high efficiency broadband GaN HEMT power amplifier (PA) are presented. Power combining was used to combine the outputs of two individual octave bandwidth 100 W power amplifiers. Optimum fundamental and harmonic load impedances were obtained using load-pull simulations for the active device across the design band. A systematic approach was applied for the design of wideband output and input matching networks.
