A note on VHF acoustically coupled bandpass crystal filters

This letter reports an experimental investigation in which the use of acoustical coupling between thickness-shear resonators to obtain a monolithic crystal filter with bandpass characteristics is extended to the VHF region and overtone operation. Attenuation curves for a 112-MHz fifth-overtone filte...
