CAD for mm-wave resonators

Abstract

The design of waveguide disc resonators for oscillators at W-band frequencies is described by the help of a finite element CAD-software package. The method considers the active device encapsulation inherently and therewith the socalled parasitic elements. The computation of output power from a standard GaAs Impatt diode for an encapsulation technique with integrated modules is given as example, The results are. compared with rf measurements at 90 GHz.
