摘要

In this letter, we propose a novel methodology for designing high-efficiency broadband harmonic-controlled power amplifiers (PAs) using a new wideband bandstop network. This network consists of many parallel open circuit microstrip lines, each corresponding to a quarter of wavelength for different frequencies. This topology can improve efficiency and bandwidth by controlling harmonic match impedance. The harmonic and the fundamental matching networks can be designed simultaneously to reduce the mutual effect between them. We also design and fabricate a highly efficient PA with more than an octave bandwidth to verify the validity of the proposed network structure. The measured results show that the fractional bandwidth is 82.9% from 1.2 to 2.9 GHz. The drain efficiency that can be achieved is 86.06% and the maximum output power is 42.97 dBm when the input power is 30 dBm between 1.2 and 2.9 GHz.
