LATERALLY COUPLED MULTI-MODE MONOLITHIC FILTER |
摘要 |
A laterally coupled multi-mode monolithic filter includes: a substrate; a piezoelectric film formed on the substrate; a ground electrode formed on a first surface of the piezoelectric film; and signal electrodes formed on a second surface of the piezoelectric film and arranged in parallel to each other, the second surface being opposite to the first surface, each of the signal electrodes including a first electrode finger and a second electrode finger, wherein the first electrode finger and the second electrode finger have different electric potentials; adjacent signal electrodes of the signal electrodes are at a distance from each other, the distance being greater than a pitch of the first electrode finger and the second electrode finger. |
