摘要

采用一种简化的设计方法实现了一种高效率的功率放大器。该方法仅利用小信号s参数数据。实现了一种高效率功率放大器，最大功率附加效率为68.8%，标称功率增益为8.6 dB, 7.5 GHz时输出功率为21 dBm。AB类功率放大器的高效性能来源于对二次谐波端部的合理选择。

High efficiency power amplifier design using a simplified approach

A high efficiency power amplifier is implemented using a simplified design method. The approach utilizes small signal S-parameter data only. A high efficiency power amplifier with a maximum power added efficiency of 68.8 %, a nominal power gain of 8.6 dB and 21 dBm output power at 7.5 GHz was implemented. The high efficiency performance is obtained from proper selection of the second harmonic termination for a class AB power amplifier.
