Wave Propagation on MESFET Electrodes and its Influence on Transistor Gain

A rigorous analysis of wave propagation along MESFET electrodes is presented. Both the losses caused by the channel and those caused by the finite electrode conductivity are included, together with small-signal amplification. Results from this wave analysis are used to determine overall gain. Conclusions concerning traveling-wave FET design, optimal gate width and related criteria are drawn.
