Abstract :
This paper describes a method of designing even-degree lower-sideband polylithic crystal filters which have stop-band characteristic similar to even-degree elliptic-function filters. The asymmetrical filter is obtained by adding a bridge capacitor across each of the dual-resonator monolithic crystal filter elements of a symmetrical Chebyshev function polylithic crystal filters
