Hi, I'm curious about that method. To test the output impedance of the amplifier circuit, why should we measure S21 parameter ? In my opinion, shouldn't S22 be measured? I test a 50 ohm output circuit with my VNA , the measured S22 is really not the expected 50, and S21 is close to 50. Can you t... (more) |
