The report discusses networks representing two types of acoustic structures used for filtering the composite resonator, a one-port device comprising a thin film overlay of high coupling material atop a low loss substrate, and the stacked-crystal filter, a two-port device wherein two or more crystal plates are joined together mechanically at the major surfaces to take advantage of mechanical and piezoelectrical coupling effects. Computer simulations of stacked-crystal filter designs at 10 MHz disclose that both Chebyshev and Butterworth responses may be obtained using quartz plates.
