Design and analysis of broadband microwave PIN diode switches

[摘要] ENGLISH ABSTRACT:The aim of this thesis is the analysis and design of a broadband PIN diode switch.Pin diode switches are gaining popularity in RF and microwave applications today. This is dueto their excellent switching and power handling capabilities, reliability, low cost and small size.An analysis and design procedure for broadband PIN diode switch design, using the series,shunt and compound topologies respectively, is presented.In order to do a proper switch design, accurate practical models for the components arerequired. Parameter extraction therefore formed an important consideration for this study. Aparameter extraction procedure is presented, which enables the designer to very accuratelyextract the required models for the components in the environment they operate in. Thedesigner can then do a proper design to ensure that the switch response when measured, closelycorresponds to that simulated.A compound configuration switch was designed, built and measured to confirm the validity ofthe design procedure. The results illustrate that if the extracted models of the components areintegrated into the design, the measured and simulated response compare remarkably well.
