Hi
Here is the fixed link of - CCRT-33S3O - please notice that the N.O. and N.C. ports are terminated with 50Ω resistors.
(Datasheet: http://www.teledynerelays.com/pdf/co.../CCRT-33FS.pdf )




I have one additional question please, which I did not quite understand from datasheet.


For some reason, they gave the Power handling of the Not-Terminated RF Switch:



Does it mean that in the DC-3GHz range, each of the IN, N.C. and N.O. ports can handle 80W?



Thank you again!

I'm not an RF engineer, but I AM an old engineer.
My interpretation is that only the unselected port is terminated. This would mean that, in the mode it was designed for, the termination would not have to dissipate any power. However, ifyou are using it as a multiplexer, then you will be applying power to the termination of the port that is unselected. Those terminations are spec'ed to handle 2W max. If I am right, the 80W@3GHz is only good in the forward direction.
