Abstract
New structures of slanted transducers are described. These structures are based on a variation of weighting along a filter aperture. The first quasi-rectangular structure has equal lengths but different numbers of fingers for every frequency channel. The second partially-weighted transducer comprises different weighting for lateral and central frequency channels. The use of such structure allows one to improve some filter parameters, such as insertion loss and metal pattern dimensions
