I have an application for a switch that is either open circuit or shorted. The power is 200 Watts at 2 Ghz and the switch will be 1 cubic inch in size, surface mounted on a microstrip. I have made switches like this before but only normal SPST types with low VSWR and Insertion Loss.
I have done HFSS simulations as well as ePhysics simulations (ANSOFT software that determines heating due to power application)to determine the heating inside the switch. However, results vary tremendously depending on the setup, and determining the "correctness" of the setup has been frustrating. Results have shown internal contact temperatures varying from 110 C to 200 C depending on how I set up the convection boundaries. I have been in contact with the AE's from ANSOFT, but I wonder if anyone has any practical experience with this type of application.
Thanks,
David
