Well you had better be a pretty good machinist! Why not go back to
google for microwave transfer switch, find a manuafturer who sells them
and then glean the manufacturers important specs like return loss,
isolation, insertion loss. Basiccally you are designing something like a
plumbing valve with rectangular passages. You have four possible routes
A-B and C-D and then switched A-C and B-D. Think ahead as to how you
will test this beast once it is built. You will need some microwave test
gear like a network analyser, and terminating load(s)

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,
