Hello BigBoss, thanks for your response and you helped a lot. As you said, Class-C PA is determined not only by bias condition, but also by input and output matching, load-source pull etc which i haven's considered. By the way, is the conduction angle of time domain signal the only way to identify the Class-C PA? thanks:smile:

Hello ktr, thanks for your response. Yes, the simulating figures are ideal and I should design the PA considering the overall structure. thanks again
