Synthesis methodology for the design of acoustic wave stand-alone ladder filters, duplexers and multiplexers

The user segment of wireless communication systems takes profit of the outstanding performance of filtering devices based on acoustic resonators. With a spectrum more and more occupied the design of filters and duplexers for mobile devices is becoming a challenging task. Usually, the design of acoustic wave devices is mainly entrusted to optimization techniques due to the stringent constraints imposed by the technological feasibility of acoustic resonators, and the challenging electrical specifications. A stringent transmission response and very restrictive technological factors make the designing a complex and challenging task. The objective of this work is to describe a methodology for the direct synthesis of laddertype acoustic filters: stand-alone, duplexers or multiplexers. The procedure is time efficient, precise in the outcomes and provides a deep understanding of the particular interactions between technology constraints and device performance.
