A mismatch sends up a red flag and causes the IRS computers to spit out a bill that the IRS will mail to you (these letters ...
Abstract: This work presents an embedded matching scheme on the multilayer print circuit board (PCB) for film bulk acoustic resonator (FBAR) filters with wafer-level chip-scale package (WL-CSP), which ...
Abstract: The resonant frequency of conventional thin-film bulk acoustic resonators (FBAR) is inversely proportional to the thickness of piezoelectric film. This study successfully demonstrated ...
