[NLRS] SMA Relay Power Handling?

[Charlie Betz]

Scott,

I dug out some relay catalogs I had from several manufacturers to check 
this.  The two that I had that showed power handing capabilities were from 
DowKey and Loral.  In general the power handling capability appears to 
mainly be a function of the connectors used rather than the switch itself.

While it varies slightly between the two manufacturers, in loose terms they 
indicate a power handling capability for small SMA relays of 100 - 200 watts 
at 1GHz and 25 - 60 watts at 10GHz.  Dowkey tended to be at the bottom to 
middle of that range and Loral more towards the top end.  Loral did not list 
capabilities of individual relays, but had a logrithmic chart showing 
average power of a frequency range of realys with various connector types.
