A resonator filter assembly is provided having a first wafer ( 102 ), a second wafer ( 104 ) and a third wafer ( 106 ). A plurality of pits are etched in the first and second wafer ( 102, 104 ) and arranged such that a plurality of resonant cavities ( 108 ) are formed with a coupling cavity ( 110 ) disposed between the resonant cavities ( 108 ). By altering the dimensions of the resonant and coupling cavities ( 108, 110 ), the frequency characteristics of the filter can be adjusted as desired.
