How do baw filters work
WebFBAR filter technology is complementing [20] surface acoustic wave (SAW) filter technology in areas where increased power handling capability, and electrostatic discharge (ESD) tolerance is needed. Frequencies more than 1.5–2.5 GHz are well-suited for FBAR devices. WebAug 9, 2024 · Unlike BAW filters, in SAW filters the acoustic wave and energy propagate along a single “Surface” of the substrate. As a result, the characteristics of the SAW resonator don’t rely on the substrate shape or thickness as much as BAW filters. SAW resonators can be divided into two main types: one-port SAW resonators and two-port …
