Simple model of large-signal properties of 1 W f.e.t. at 5 GHz

Extensive large-signal measurements performed on a 1 W microwave f.e.t. at 5 GHz verify that its added-power characteristics can be accurately predicted from a simple analytic model requiring only two large-signal measurements for each frequency of interest. This model makes possible the use of linear circuit theory to design broadband matching circuits for optimum added-power performance.
