Hello Microwave Forum,
I am trying to incorporate a RF power detector in my circuit at C-band to understand if a discontinious cable or a rusty connector exists between my antenna and PA.
I have a circulator after my PA to protect the circuit for reflections. Circulator's unused port is terminated with 50ohm to dissipate the power reflected from mismatches(normally). I want to show a 50 ohm termination to that port while simultaneously sampling the power in-line with a detector.
---Can I use a 0 db attenuator to show circulator's 3rd port 50 ohm termination while sampling the reflected power with a RF power detector. I tried drawing a schematic where normal lines are forward power and dashed lines are reflected power in case of a discontinuity, is this logical?
Kind Regards,
ktr
