SURFACE ACOUSTIC WAVE DEVICE HAVING END-TO-END COMBINABLE SELECTABLE ELECTRODE SUB-ELEMENTS

摘要

A described surface acoustic wave device includes a piezoelectric substrate and a configurable electrode assembly. The assembly includes: an array of N rows of M electrically isolated elongated electrode sub-elements arranged end-to-end in columns; a first signal bus proximate to the first row of the N rows; a first matrix of row addressable switches configured to electrically couple the first signal bus with a respective electrode sub-element of the first row of electrode sub-elements; a second signal bus proximate to the Nth row of the N rows; a second matrix of addressable row switches configured to electrically couple the second signal bus with a respective electrode sub-element of the Nth row of electrode sub-elements; and a plurality of addressable column switches, each addressable column switch respectively configured to electrically couple an electrode of a column of the M columns with an end-to-end adjacent electrode of the same column.
