VSWR Sensitivity to a Power Amplifier - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Good day.

The power amplifier is using 2 HFETs (WJ FP31QF). The input signal is split using a 3 dB Quadrature Hybrid (Anaren 1E1304-3), fed to the transistors and then combined with another 3 dB Quadrature Hybrid (same hybrid). My question is what effect would a mismatch have on the transistors? Would they see the mismatch or would there be some isolation?

Thank you for your time and help
Michael
