Any one can help me, In AWR software
Problem:i have design interdigital capacitor but this capacitance value is varied by varying the frequency. in normal distributed capacitance value is constant. [/B]
my work is i have design a distributed filter circuits i have try to replace distributed capacitance place the designed interdigital capacitor,but its scattering parameters, capacitance and quality factor is varied so im struck to get desired result.
Thank you

Do you have a reference for this? As far as I'm aware, most printed capacitances are frequency-depedent.
Value is constant only if your ICAP is small compared to the wavelength. And even when small, it has some series inductance that results in frequency dependence.
