A novel filter device, employing bulk waves, has been demonstrated experimentally. Inherently simple in construction, miniature and robust, it provides bandwidths of several percent at HF with low insertion loss. Known as the stacked-crystal filter, the new device employs crystal plates bonded together into a sandwich-type structure. This novel structure offers the promise of broad-and medium-bandwidth acoustic filters in frequency regions where such characteristics are unavailable with conventional single element crystal filters. To date, experimental effort has been primarily placed upon achieving this improvement in the region below 10 MHz; consistent with this, a goal of less than a few aB insertion loss appears feasible in most cases.
