  • Abstract
    Power flow angles (PFAs) on the langasite (LGS) substrate with Euler angle of (0deg, 138.5deg,Psi), Psi = 25.7deg to 27.7deg are investigated for slanted finger interdigital transducer (SFIT) SAW filters to realize an optimum design. A tilted 380 MHz SFIT SAW filter with an aperture of 40 wavelengths and number of finger pairs of 500 for input and 300 for output is designed for the appropriate PFA of the substrate and a good frequency response is obtained
