That's a 0.2 pF capacitor. Z at 5 GHz is 159 ohms. Perhaps you intended to
use a larger value? Such small caps are more often used for shunt tuning.

Subject: [SI-LIST] Capacitor S parameter
Hi Experts,
Currently I'm doing a RF Signal S-parameter simulation.
One series capacitor is connected with RF Signal trace near the DUT side.
RF Signal operating frequency is 5GHz.
I downloaded s parameter(.s2p) model from manufacturer website (
http://psearch.murata.com/capacitor/product/GRM1555C1HR20BA01%23.html[1] )
Capacitor part no:GRM1555C1HR20BA01
The insertion loss (S21)is very high up to 10 GHz.
Is this capacitor support 5GHz or
this capacitor allows only above 10GHz Signal?
How can i choose the capacitor which supports 5GHz?
Looking forward for SI Experts answers.
Thanks,
Sukumar
