Hello, I have a few questions on couplers. I want to sample both forward and return signal. In one website I visited concerning couplers, they said you should use 2 couplers back to back, but this adds insertion loss, and I don't like that. Can't I just use one? Also, I assume all ports should be terminated into 50Ω, am I correct? So which way is correct in my attached image?
Thanks
Thanks
