Abstract

A specialized type of traveling-wave field-effect transistor (TWFET), the gate and drain lines of which contain series capacitors, series inductors, shunt capacitors, and shunt inductors, is considered to provide a platform to manage unattenuated dispersion-free envelope pulses. Because of the nonlinearity caused by the gate-source Schottky capacitance, the dispersive distortion is well compensated. Moreover, the FET gain can cancel the wave attenuation caused by electrode losses. This paper discusses the design criteria of a TWFET using the nonlinear Schrodinger equation obtained by perturbation. Several numerical calculations follow to validate it.
