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...

| description | 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 filter with a bandwidth of 14 kHz are given, showing good stopband performance over the 10 to 300 MHz range of measurement. |
