Simulation of parametric sensitivities
Acoustic components used for filtering

Simulating the parametric sensitivities of surface or volume wave components for filtering is a crucial step in the computer-aided design of passive acoustoelectric frequency filters. Optimizing the temperature coefficient of the first-order frequency (CTF1, static thermal effects) radically conditions whether or not it is possible to meet a filter specification in terms of compliance with the template over the temperature range, generally extending from – 40 to + 85 °C as specified in [E2000] .

There are two distinct approaches...
