Abstract :
Field-theoretical results of high-frequency MeSFET structures are presented on the basis of a mode matching technique. Wavelengths and attenuation constants are given for frequencies from 1¿100 GHz. An experimental approach with 3.2 mm transverse-length MeSFETs confirms the theoretical data. It is pointed out that such results are useful in modelling mm-wave transistors suitable for frequency ranges above 20 GHz.
