Electroacoustic characterisation of +64 degrees and +41 degrees Y-rotated LiNbO/sub 3/ for wide bandwidth low loss filter design
Acoustic propagation on metallized surface high-coupling-coefficient 64 degrees and 41 degrees rotated Y-cut LiNbO/sub 3/ was investigated experimentally and theoretically. A complete set of experimentally determined acoustic parameters in the 0.85-tp-1.6-GHz frequency range is presented. 11.6% and 21% coupling constant values have been deduced from transducer admittance measurement for 64 degrees and 41 degrees LiNbO/sub 3/ respectively. These data have been applied to the design of 1-GHz image impedance connected low-loss filters. 7% and 10% 3-dB fractional bandwidth was obtained with 8- and 13-dB insertion loss on 64 degrees and 41 degrees LiNbO/sub 3/, respectively.<>
