Abstract
This invention relates to high efficiency class E power amplifier optimizing design method including: a given system parameter: output power Pout, power voltage Vdd, working frequency f and output Q value OL(=2 pi F*/RL) and setting RL* the largest value (RL): to calculate elements C1, L1, and RL to get value C1*, L1* and RL*, then further calculate L2, C2, with numerical analysis method calculating reactance element value jx to simplify class E PA traditional design to get the largest optimizing load so as to reduce the matched network loss in creasing the entire efficiency of PA.
