Design and Synthesis of Surface Acoustic Wave Ladder-Type Filter

There are three kinds of Surface Acoustic Wave (SAW) filter design which are the Interdigitated Interdigital Transducer (IIDT) type design, Double Mode SAW (DMS) type design and ladder-type design. However, this study will focus on the SAW ladder-type filter as filter synthesis approach is applied t...
