Hi, I have a question about RF LNA chip test procedures.
The LNA have been soldered on the PCB, with RF in, out connected to SMA connectors, and DC pin to regular connector. It is self-biased MMIC LNA operating at 5.8GHz. In order to test its small signal gain and P1dB, what are the test procedures? Can somebody check the following procedures correct or not?
1. Adjust the network analyzer output power lower than a certain level (-10dBm in my case, which the LNA gain is 20dB, and P1dB is about 20dBm). Make the SOLT calibration for the network analyzer.
