Default Choice of DC blocking Capacitors in Microstrip Design


I was wondering as to how to choose the correct value of a DC blocking
capacitor with least possible reactance with atleast 5V and 20mA.
Center Frequency 910MHz. The value of capacitor that i need is above
200pF..

I know the thumb rule that SRF(self resonant frequency) 2 Operating
frequency. but i enquired both Farnell and Rscomponents distributors
in UK as am here .., Only low value capacitors satify the above
criteria of SRF. How do i proceed with the same...

Thanks a lot
Alec


Well, you might try paralleling a bunch of little ones.
