Analytical modeling and design criteria for traveling-wave FET amplifiers

The theoretical modeling and design of a traveling-wave FET are described. The device shows the capability of wide-bandwidth performance and high gain and could be useful in power applications. The proposed analytical model considers the full mode effects of the three-coupled transmission lines and an accurate analysis of the FET model in the traveling-wave amplifier. Starting from electrode dimensions and active zone doping, such a model allows one to calculate the scattering parameters. Thus, it is possible to analyze the device as a six port network in a circuit analysis program.<
