Abstract

In general, a LCR (longitudinally coupled resonator) filter design requires a complex non-linear optimization procedure. The effectiveness of such a procedure depends both on the performance of the optimization algorithm, and on the underlying model of the device. This paper describes a general procedure for optimizing LCR filter responses by applying non-linear programming techniques directly to a Green function device model. A simplified Green function analysis procedure has been developed that is extremely accurate and is also efficient enough to be used directly in optimization. The method has been applied successfully to both SAW and leaky wave filters
