Re: [Microwave] 0.5pf "feedthru" capacitor?



In American, "feedthru" means a DC connections with capacitance to
ground. In British, at least for those filters, "feedthru" means a
capacitor that passes signal through the shield with minimal capacitance
to ground. What you need is to first find a 1/2 pf capacitor (or find
some 1 pf and run two in series) and use the body of the capacitor to
plug a hole in the shield. E.g. make a hole in the shield and "feed" a
small capacitor "through."
