I have tried to simulate a stripline whose characteristic impedance (Z0 = 14.75729574 Ω) can be calculated analytically, but the simulated S-parameter values do not make sense.
I followed the example…

## Just an Observation Posting
### Background
1. The DUT & fdf (fixture dut fixture) that I had simulated & measured has about >15 dB return loss @20 GHz.
2. The s2xthru (fixture to fixture) i…

Hi,
I've got a question about possibility to improve cauer filter calculator.
I tried to design low pass filter and I noticed that only "pi type" is available (even if "tee type" is selected) and on…
