Given I have designed and produced an RF circuit with an output for connecting an antenna. I know this antenna has an input impedance of 50Ω. I now wish to measure the actual output impedance of my circuit, before connecting the antenna, to ensure that the impedance matches.
How do I actually measure the output impedance of my circuit?
And additionally, can I do this with hobby friendly priced equipment?
Update: I know the basic theory of impedance matching, but I have never understood how to actually do it. So I am really asking for input on the specific hardware and equipment to use, and how to perform actual tests.
The RF circuit is operating in the UHF range, and transmits about 10dBm, if this helps.
