Multilayer piezoelectric substrate resonator reflector stopband setting

Abstract

Aspects and embodiments disclosed herein include a radio frequency filter including a plurality of surface acoustic wave resonators. At least one of the plurality of surface acoustic wave resonators is a notch resonator electrically connected to others of the plurality of surface acoustic wave resonators in a shunt configuration and having a resonant frequency above an upper end of a passband of the filter to improve signal rejection at the upper end of the passband of the filter.
