I am looking at dc blocking caps at 24 GHz. I am having a tough time finding the capacitors that have their SRF above 24 GHz. So, I was looking at interdigital caps using microstrip lines at 24 GHz. My substrate is Rogers 4350B, thickness is 0.254 mm. I would like to design an interdigital capacitor for 0.33pF and 0.39pF. Could anyone provide the design methodology for this interdigital capacitor. This capacitor will be used as a DC block in an LNA application using CE3520K3 FET.
