Re: Info Need on a RF FET for a Agilent E4438C signal generator
Hello Lothar I do not need 27dBm output. As it is not the final Fet. but I think the gain of the SHF-0189 is too little. It has around 20dB at low freq but only 10 to 12dB at 4Ghz. so I might need

I realized a couple of hours after sending the initial post, that I was incorrect with associating Calibration with the Port Extensions. Here is, I hope a better explanation of what I am trying to do.
