Hi everyone. I'm trying to design a particular microwave switch. The basis are very simple: just a diode bridge that lets pass through one microwave signal or dont, according to a clock signal.
The particular conditions are: the microwave signal has a BW from 2.5 to 4 GHz, approximately, and the clock signal is at ON state only for 6 ns.
I've searched among a lot of distributors but it's very difficult to find a diode that accomplish with the 6 ns constraint (=switching time or reverse recovery time). I've tried it with both schottky and pin diode, but no of them gave me the good result. If possible, the diode should be encapsulated, not monolithic.
so, any idea? maybe the diode bridge is not a good choice?
Pleaseee, i need help, i'm getting hpeless.
thanks for your help.
