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
