Popis:	Surface Acoustic Wave (SAW) filters are a key device for mobile communication systems, and the high performance and low-loss of SAW filters has been increasing rapidly. The general design procedures for practical SAW filter are a trial-and-error approach by expert designers. The researches on the design of SAW filters using some different optimization algorithms (i.e. variable neighborhood search) have been the local search method so far. In these researches, the SAW filters are IDT type. Recently, the front-end with ladder type filter has proposed. This filter is low-loss type. The research of the ladder type SAW filter design using the optimization algorithm has not been performed. So, this paper proposed the design method of a ladder type SAW filter using simulated annealing.
