Computer Simulation of Switching in Microwave Pin Diodes

TLDR: In this paper, computer simulations have been carried out of switching behavior and design optimization of microwave PIN structures used in millimetre-wave communications, using an implicit iterative method to obtain the internal distributions and terminal response of PIN diodes in a simple, but realistic circuit.

Abstract: Computer simulations have been carried out of switching behaviour and design optimization of microwave PIN structures used in millimetre-wave communications. The simulation operates in the time domain and uses an implicit iterative method to obtain the internal distributions and terminal response of PIN diodes in a simple, but realistic circuit. The use of the program as a research tool aimed to the understanding of the internal processes, and also as a design tool for the optimization of the diode structure, will be presented together with a comparison of the computed results with those measured experimentally.
