Abstract :
Acoustic surface wave resonators have been used extensively in narrow band applications. In this paper new SAW resonator structures are described, which have the same impedance characteristics over a large band as bulk wave resonators operating at fundamental frequency. Theoretical and experimental results obtained for those SAW resonators show that they can readily be incorporated in large bandwidth ladder or lattice filters for VHF frequencies.
