Abstract:
1. A device comprising: a matching network including first and second voltage tunable capacitors that share a common electrode; and a bias element coupled with the matching network, wherein the bias element applies a first bias voltage to a first electrode of the first voltage tunable capacitor, wherein the bias element applies a second bias voltage to a second electrode of the second voltage tunable capacitor, wherein the common electrode is unbiased, and wherein the applying of the first and second bias voltages causes the first and second voltage tunable capacitors to vibrate in opposite phase to each other, wherein the first and second voltage tunable capacitors comprise: the first electrode and the second electrode positioned in lateral proximity to each other, the common electrode positioned opposite to the first and second electrodes, and a single tunable dielectric layer positioned between the common electrode and the first and second electrodes to form the first and second voltage tunable capacitors that are acoustically coupled together.
