Hi DeboraHarry,
Thanks for replying. What I have is a 50 ohm line going into a transformer that is meant for a 75 ohm system, that then connects to a differential amplifier.
so basically you go into the transformer single ended then after the transformer you have that diff amp, and at the output of the diff amp there is another transformer that converts it back to single ended.
I thought about a quarterwave line, but I dont have board space to work with.
Also, can you tell me, from first principles, what should I be expecting to see on the network analyzer when you have matched a particular port? What would S11 look like when I connect the input to the network analyzer?
thanks,
DK
