I want to connect signal generator to coaxial cable.This signal generator has output impedance 50 ohm and it is not matc with coaxial(75 ohm).I want a ciruit to match them.
Technically speaking it's possible.
Economically speaking it isn't convenient.
This beacase both the solutions proposed, especially the minimum loss pad are lossy and expensive solutions.
The 75 Ohm cable has lower loss (with same outside diameter) than 50 ohm cable, but with 2 minimum loss pad or 2 transformer you lose more that the gain!
Also consider that for a good match you need coaxial connectors.
Each pad or transformer need a couple of connectors (1 50 Ohm, the other 75 Ohm).
