Patent abstract
A method for switching a bulk acoustic device is disclosed. The bulk acoustic device has a substrate, a first electrode, a second electrode, and a piezoelectric film between the first and the second electrode. Switching is obtained by controlling the polarization of the piezoelectric film, through application of a DC voltage difference to the first and second electrodes. Therefore, no additional switches are needed to direct and control the RF signals passing through the device.
