This filter passes a range of frequencies close to the resonance frequency of the LC pair (shown at the lower right). These filters would not only reduce the transmitted noise spectrum from each exciter, but would reduce receiver front-end overload problems as well, because each operating position would transmit and receive through a band-pass filter. 3 Method In realization of such a bandpass filter, the main questions we faced are the very low insertion loss in passband with extreme high operation power, the suppression of the 2nd and 3rd harmonics, and the linearity of the phase response. f c = 1/2π√(LC) Where L = inductance of an inductor whose units are in Henry (H). In low-pass and high-pass filters, each branch is either a capacitor or an inductor. Moreover, books with tables adjusted for non-optimum Q (“predistorted”) are specialized and somewhat expensive at $70 and up used.
