measure output impedance pa network analyzer
I have vector network analyzer, which can measure input impedance.
I just put device on port 1, and measure the S11, then can get Zin from S11.
For there is no output power from the device in port, and the measured power is just the reflect power, which is a portion of port1 output from the analyzer.
But some device can out put power, such as PA, LNA, and etc.
How to measure the output impedance of them?
Thank U!
