“…22 However, during the past decades, few works have been reported on the research and analysis of the effects of the bias networks on the PA design, especially the influence of bias microstrip lines (BML) circuit for board level PA design. [23][24][25][26] In addition to stabilizing the static operating point, the BML circuit can also greatly affect the harmonic impedance, [27][28][29][30][31] leading to a concave phenomenon in the performance curve. 32 As a result, numerous experiments were conducted, and an in-depth analysis of the concave phenomenon was presented in this study.…”

In this paper, the impact of the bias networks on a radio frequency (RF) power amplifier (PA) is analyzed and discussed comprehensively. Both the different sizes and positions of the bias microstrip line circuit have been studied for a broadband class AB PA. Both simulations and measurements show that the performance of the PA can be greatly improved with the adjustment of the bias circuit by effecting the harmonic impedance of the whole matching circuit. Compared with the existing works, the fabricated PA based on the proposed technique provides the best performance, thereby demonstrating the effectiveness of the developed bias circuit optimization method.
