WebSAW devices are used as filters, oscillators and transformers, devices that are based on the transduction of acoustic waves. The transduction from electric energy to mechanical energy (in the form of SAWs) is … WebApr 4, 2024 · SAW filters operate by converting electrical energy into acoustic or mechanical energy on a piezoelectric material. To do so these filters uses interdigital transducers (IDTs). The IDTs have interleaved …
WebJan 22, 2016 · SAW devices work best at lower frequencies below 1.5 GHz, while BAW technology works best for filter designs above 1.5 GHz. In today's mobile environment, the amount of bands required in one device is staggering — and the trend will only increase. Supporting all these bands causes coexistence issues requiring filters to reject bands, … WebBAW filters typically operate at frequencies from around 2 to around 16 GHz, and may be smaller or thinner than equivalent SAW filters. Two main variants of BAW filters are making their way into devices: thin-film bulk acoustic resonator or FBAR and solid mounted bulk …
