Good Morning, for my thesis I've to design a transfer switch operating between 8 and



14 Ghz, I would want to ask you where I could found a little bit of tutorials on this theme in a way to avoid many stupid questions for you. I've already searched on google but I've found just commercial information while I'm interested to schemas and designs consideration on this topic.

Many Thanks for your help,



Antonio D'Ottavio

Schematics ? What do you want schematics for ? The structure of a switch is known. You just have to decide on the isolation. This then determines how many diodes you'll take. The detail lies in the geometrical layout.

Well not really, it could be a reflective switch or absorbtive switch. Obviously, one reflects the signal not switched in, the other doesn't. (I'm assuming we're talking about PIN diode switchs)

A couple of tuned PIN diodes and resonant cavities, with proper waveguides, should do the trick.

Why hasn't the teacher covered this part of the course?

Thanks, Rich
