Hi
I would like to ask that. Usually i found the diode model can be respect by resistance and capacitance. Since diode is a non-linear device. the impedance characteristic is vary with the biasing voltage. so it mean the the S-parameter also vary with the biasing voltage? When i want to test...
Hi
How to measure the open loop gain of an amplifier using the gain-phase analysis? Since the output signal of the gain-phase analysis is large 126uV, if the amplifier have 120dB gain, the output of the amp will be saturated. So have any technique to measure the gain-phase in open loop gain?
Re: RF schottky
If i bias the diode with a dc voltage through a inductor, and connect the network analyzer with a dc blocking cap, for this setup can it measure the S-para correctly if the network analyzer cannot provide a large power level during measurement?
Thank a lot

Hi
I would like to ask how to measure the S-parameter of schottky diode?
is it just connect the anode pin at to signal pin and the cathode pin to ground at the network analyzer?
