In the paper, an improved method for the simultaneous determination of GaAs FET noise figure and available power gain is given a method for the design of loss matching network and quantitative analysis of its loss is also presented.

Based on the stability theory, the functions of the nonlinear feedback control for synchronization of these systems are determined and the range of available feedback gain is derived.

根据系统稳定性理论，得到了非线性反馈控制器的结构和系统达到混沌同步时反馈控制增益的取值范围。

Determination of GaAs Microwave FET Noise Figure and Available Power Gain
