Abstract
The effect of the dielectric loading in a bidimensional analysis that follows. GaAs traveling-wave amplifier (TWA) is investigated, with respect to the EM power generated by the structure and the efficiency of the dc to RF conversion. The validity of some usual approximations and assumptions is studied and a parameter, i.e., the power gain X efficiency product, is proposed as a useful tool for comparing the possible performances of TWA´s.
