SURFACE ACOUSTIC WAVE DEVICE HAVING MATRICES OF COMBINABLE SELECTABLE ELECTRODE SUB-ELEMENTS

摘要

Described embodiments include a surface acoustic wave device, method, and apparatus. The device includes a piezoelectric substrate and a configurable electrode assembly. The assembly includes N stacked instances of electrode assembly sub-units. Each electrode assembly sub-unit includes: a plurality M of elongated electrode sub-elements electromechanically coupled with the piezoelectric substrate; an electrically isolated first signal bus crossing each of the electrode sub-elements; a first matrix of individually addressable switches, each addressable switch of the first matrix configured to electrically couple a respective electrode sub-element of the plurality M of electrode sub-elements with the first signal bus; an electrically isolated second signal bus crossing each of the electrode sub-elements; and a second matrix of individually addressable switches, each addressable switch of the second matrix configured to electrically couple a respective electrode sub-element of the plurality M of electrode sub-elements with the second signal bus.
