Synthesis procedure for ladder acoustic wave filters starting in series resonator

This work provides a new procedure to synthesize acoustic wave ladder filters starting with series resonators. The novelty of this method relies in a new synthesis methodology to extract a series inductance in filter configurations starting in series resonators. As a matter of fact, this new synthesis provides solutions with a reduced value of the electrostatic capacitance, thereby giving resonators with smaller size.This work have been supported by the Spanish Government through grants TEC2017-84817-C2-2-R, TEC2017-88343-C4- 2-R, the Secretary of Universities and Research of the Generalitat de Catalunya through 2017 SGR 813.Peer ReviewedPostprint (author's final draft
