The design of microwave power amplifier needs large-signal s parameters, but under most circumstances, the designer only has small-signal s parameters and the static I-V curve.

微波功率放大器设计需要大信号s参数，但大多数情况下，设计者只有小信号s参数和静态I - V曲线。

We developed a general large signal modeling software and extracted the power FET model parameters. The parameters are well coincide with simulated and measured large signal s parameters.

用研制出的大信号建模软件提取了功率FET的大信号模型参数，并用该模型模拟和测量了器件大信号s参数，结果完全一致。
