A design routine is reported that optimizes the power-added efficiency of a class B microwave amplifier stage. The measured data required consists of device I-V data and one large-signal gain measurement at the microwave frequency of interest. The me

This paper presents normalized wide-bandwidth measurements of microstrip effective relative pemrittivities (epsilon/sub eff/) which were made on large-scale microstrip models. The experimental techniques are discussed, and the data are compared to th

The small-signal analysis of a distributed IMPATT diode ifdicates the existence of a traveling-wave mode. The severe power-frequency limitation as well as the associated low impedance level of the discrete diode appear avoidable. No external resonant

The coupling between a microstrip and a distributed IMPATT diode was investigated in a field analysis. An effective wave impedance in the traveling wave diode can be defined as the ratio of the space-average transverse electric and magnetic fields. T

The diffraction loss of a new low-loss waveguide for millimeter and shorter wavelength, called the beam waveguide, was measured. The loss measurements were made using a resonator technique. The beam waveguide resonator derived from the beam waveguide
