摘要

本文介绍了一种广义连续谐波调谐功率放大器的设计方法。将阻性-无功连续f类模和阻性-无功连续反f类模相结合，提出了一种更广义的连续模。放宽了严格的谐波阻抗终止条件。此外，由于非线性电容的影响，设计更加注重基本阻抗的匹配。并在此基础上设计了一个宽带扩音器。在2.4 ~ 3.75 GHz范围内，输出功率大于12W，增益大于11dB。在整个设计范围内，漏极效率(DE)在66% ~ 71%之间。

A method for designing generalized continuous power amplifier

In this paper, a method for designing generalized continuous harmonic-tuned power amplifier (PA) is introduced. A more generalized continuum mode is presented by combining the resistive-reactive continuous Class-F mode and resistive-reactive continuous inverse Class-F mode. The strict harmonic impedances termination conditions are relaxed. Also, as the effect of the nonlinear capacitance, the design focus more on the fundamental impedances matching. And a broadband PA is designed based on this method. The output power is more than 12W with the gain over 11dB form 2.4 to 3.75 GHz. And the drain efficiency (DE) is from 66% to 71% across the design band.
