INTRODUCTION T HE advent of 5G and the desire for large bandwidth has brought the 3–30-GHz band into prominence [1]. RF MEMS piezoelectric film bulk acoustic resonators (FBARs) [2], the gold standard of 4G filter technology, WebMar 1, 2024 · Therefore, in this range, bulk acoustic waves (BAWs) compete with SAWs. One of the ways to excite BAW in the gigahertz frequency range is the use of a high overtone bulk acoustic wave resonator (HBAR) [ 15, 16, 17, 18 ]. Currently, the HBAR working frequency up to 40 GHz has been demonstrated [ 19 ]. literacy in american society
