Ladder-type surface acoustic wave (SAW) filter is commonly used RF filter in many communication systems. The circuit structure of a ladder-type filter consists of several one-port SAW resonators on a piezo-electric substrate arranged in series and parallel alternatively. The bonding pads of the one-port SAW resonators and the internal connections may present a significant influence on the performance...
Electronic packaging has a significant influence on RF surface acoustic wave (SAW) device. Hence, how to incorporate packaging effects into SAW simulation is an important issue. In this paper, neural network was employed to determine the lumped element models of bonding pads. As an example, an RF SAW filter used in GPS system was examined. The result showed a good agreement with that obtained from...
