Abstract
A cross-coupled bandpass filter includes first, second and third resonators such that a positive mutual inductance is generated between the first and third resonators and mutual inductance generated between the first and second resonators and mutual inductance generated between the second and third resonators have the same polarity, thereby generating a transmission zero in a high frequency rejection band.
