Abstract
Examples of a capacitive-coupled bandpass filter include a plurality of coupling capacitors connected in series along a signal path extending between an input contact and an output contact, a first harmonic suppression notch circuit configured to provide a first harmonic suppression notch in a frequency response of the capacitive-coupled bandpass filter, and a second harmonic suppression notch circuit configured to provide a second harmonic suppression notch in the frequency response of the capacitive-coupled bandpass filter. The first harmonic suppression notch circuit includes a first pair of series L/C resonators connected in shunt between the signal path and a reference potential, and the second harmonic suppression notch circuit includes a second pair of series L/C resonators connected in shunt between the signal path and the reference potential.
