Abstract:
1. A method of designing an acoustic microwave filter in accordance with frequency response requirements, comprising: selecting an initial filter circuit structure including a plurality of circuit elements comprising at least one resonant element and at least one other reactive circuit element; selecting lossless circuit response variables based on the frequency response requirements; selecting a value for each of the circuit elements based on the selected lossless circuit response variables to create an initial filter circuit design; transforming the at least one resonant element and the at least one other reactive circuit element of the initial filter circuit design into at least one acoustic resonator model to create an acoustic filter circuit design; adding parasitic effects to the acoustic filter circuit design to create a pre-optimized filter circuit design; optimizing the pre-optimized filter circuit design to create a final filter circuit design; and constructing the acoustic microwave filter based on the final filter circuit design.
