thanks for replying biff.
I usually use SOLT mechanical calibration kit.
I measure the S-parameters which contains both the response of DUT and the fixture. Later i de-embed by removing the fixture effects in ADS.
I follow this method: **broken link removed**
I have done this already. Now...
I am going to design a test fixture to measure the S-parameters and later de-embed in ADS. I have one question:
1. Does the electrical length of the lines in the fixture have to be less than 90 degrees?
Thanks in advance.
actually I haven't. I am completely new to RF, specially have no idea about how to do s-parameter measurement successfully. If the transistor does have self oscillations, then is there any way to avoid it?

thanks. I will try this out.
Thanks a lot for your reply.
The device is an unmatched and packaged device. The gain given in the datasheet is small signal gain. So I believe it is a small signal device. The RF input power for the transistor (or the output from network analyser) is indeed 0dBm. Do I need any higher value...
I have been trying to measure the S-parameters of GaN HEMTs and LDMOS. but some reason I haven't been able to get expected values. I am not really sure of the reason. For example: in cold FET or below pinch-off measurement(Vgs<below pinch-off and Vds=0V), S11 parameter should be purely...
Does anyone one know how to optimize the source impedance for P1dB in ADS?? There is one design guide to find the load impedance at different gain compression. But I need to find the source impedance as well for P1dB. I would really appreciate any kind of help or suggestion :)
i tried, but i can't manage to get the exact values of Zs and Zl given in the datasheet. that's why i was wondering if there are certain ways to get the Zs and Zl for max PAE or max output power.
Hi everyone, here is my problem!
I have the ADS model of a transistor. In the datasheet of this transistor, the Zs and Zl for five different frequencies are given and stated that these values are optimized for power, gain, PAE and Psat. So I have been trying to find these exact values of...
