RF res,cap?
in the @DS component library none of the capacitors have SRF more than 6-7 GHz. How to design a capcitor which has SRF more than 10 GHz or what can be alternate to this?
thanks
/k
I want to design a capacitor in @DS as the capacitors available in the component libray have SRF around 6-7 GHz but i need a capcitor working till 11 GHz so can some one tell me how can i design it and how much time will it take as i have very short time.
