AT-Cut Quartz Piezoelectric Transformers for Passive Voltage Gain in an RF Front-End

Circuit Editing of Gold Connecting Electrodes using a Focused Ion Beam Microscope

“…Colleagues from the US Army Combat Capabilities Development Command (DEVCOM) Army Research Laboratory (ARL) Energy Sciences Division have designed a piezoelectric acoustic resonator for possible use in communications devices. 1 This design utilizes multiple gold electrodes deposited on a thin (5-50 µm) AT-cut quartz substrate. When an alternating voltage at the resonant frequency appears across gold pads on either side of the substrate, the quartz vibrates in thickness-shear mode resonance.…”
