    guys here is a band pass filter " http://en.wikipedia.org/wiki/File:Bandpass_Filter.svg "
    i want to filter 95Mhz from a oscillator! so should be the resonance of tank circuit of the filter should
    be 95Mhz in order to pass only 95MHz...
    for example 180nH and 15pF makes 95Mhz...so the values of the three inductors should be 180nH and the all three capacitors be 15pF...am i right.please help me!

    In theory you're probably right. In practice you'll want to make the capacitors (or inductors) adjustable to accomodate different non-resistive drive & load impedances.

    This is looking like a school task, which you obviously should be solving in a different manner than this..
