VSWR Sensitivity to a Power Amplifier - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

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

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
