  • Abstract
    Low-loss, low-ripple and high out-of-band rejection SAW filters have been constructed using a three transducer configuration with symmetric/antisymmetric end transducers. The filter on 128°-cut LiNbO3 has an insertion loss of 5.2 dB, a passband ripple of 0.3 dB (peak to peak) and an out-of-band rejection of 55 dB.
