Abstract
Aspects and examples provide improvement in the attenuation level near the passband within the stopband of the bandpass-type filter using a ladder-type circuit. In one example the ladder-type circuit is formed from bulk acoustic wave resonators. A loop circuit is connected between two distinct points on a signal path extending from an input to an output of the ladder-type circuit for phase-cancellation of signals at the two distinct points. The two distinct points may be the input and the output of the ladder-type circuit. The loop circuit may include a coupled bulk acoustic wave resonator.
