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
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: VSWR Sensitivity to a Power Amplifier
postPosted: Fri Jun 24, 2005 4:02 pm
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?
you for your time and help
