Abstract :
A numerical synthesis procedure for low-loss surface acoustic wave devices has been adapted to microwave filters. Multiple reflections and energy depletion are allowed for, permitting relatively large amounts of energy to be drawn by the taps. Using the synthesis procedure, quasi-transversal filter design has been demonstrated for linear phase microwave filters. A copper filter has been produced with performance close to design and a YBCO superconducting filter has shown encouraging results.<>
