Abstract

See full text

A cross-coupled bandpass filter includes first, second, third and fourth resonators such that magnetic couplings are generated between the first and second resonators, between the third and fourth resonators and between the first and fourth resonators, a capacitive coupling is generated between the second and third resonators, and the magnetic coupling between the first and fourth resonators has a polarity opposite to that of the capacitive coupling between the second and third resonators, thereby generating two transmission zeros in a transmission rejection band.
