I am a mechanical engineer that has been tasked with verifying that a bunch of RF elements in a circuit are impedance matched. I have a source component with a 50 ohm output resistance that connects via SMA to another element with a 50 ohm input resistance.
The data sheet says that the connection is SMA 50 ohm. Forgive my ignorance, but is this referring
to strictly the characteristic impedance of a single metallic connector where the coax cable has an additional 50 ohm impedance, or
is the 50 ohm figure referring to the cable and the two connectors in total?
From what I have read today, if it's case 1, then that is an appropriate impedance match, but if it's case 2, then I would effectively have an output resistance of 100 ohms connected by 50 ohm coax to a 100 ohm input impedance and have an impedance mismatch. Thanks!
