Abstract
Description
本願は、2015年11月13日に出願された米国仮出願第62/255,113号、2016年9月22日に出願された第62/398,416号、および2016年11月2日に出願された米国出願第15/342,045号に対する優先権を主張するものであり、各々の全体の内容は、参照により本明細書中に援用される。
RFフィルタは、ある性能指数(FOM)を使用して評価されることができる。1つのそのようなFOMは、品質係数(Q)であって、別のそのようなFOMは、有効結合係数(K2)である。Qは、材料の機械的損失の測定値であって、直接、フィルタ挿入損失に関連する。Qは、圧電材料の識別および品質ならびに圧電媒体と基板との間の隔離の有効性の関数である。K2は、圧電結合の有効性の測定値であって、フィルタの帯域幅を判定する際に重要である。
fr=vs/(2*tf) [1]
式中、frは、周波数であって、vsは、圧電層を通した音速であって、tfは、圧電層厚である。
