The design for the bandpass filter I'm studying at the moment is detailed here and here.

I can't seem to wrap my head around how to go about selecting the capacitors for the circuit - It took some playing around to find capacitor and resistor values that are actually available commercially, what trips me up are the tolerances.

For example: a 100 Ohm resistor and 7.4 pF capacitor would result in the lowpass side of my filter having a cutoff frequency of 215mhz. Perfect, because I want the highpass side to cut off at 217 (so my center freq. equals sqrt(215*217) = approx. 216). However, the tightest tolerance I can find for a 7.4pF ceramic cap. is +/- .1pF - So unless I bought a bunch and binned them myself to find one that's dead nuts on @ 7.4pF, my lowpass side is actually going to have a cutoff at anywhere from 212MHz (7.3pF) to 218MHz (7.5pF). Best case I skew the center frequency off its mark, worse case I end up with a bandpass filter without a passband.

How do I deal with this? Is this design more of a theoretical construct, and is there perhaps a similarly simple design that can use components with less stringent tolerances?
