ABSTRACT:
A spectrum analyzer incorporates a 36.degree. Y cut lithium niobate Bragg cell provided on one face with an interdigital transducer. The 36.degree. Y cut maximizes the ratio of quasi-longitudinal to quasi-shear wave piezoelectric coupling with the interdigital transducer and thereby minimizes the output of spurious signals from the analyzer. In a preferred embodiment the Bragg cell comprises two lithium niobate crystals bonded by a metal (preferably gold) film, the crystal attached to the transducer being 36.degree. Y cut and the other crystal being cut so as to maximize acousto-optic coupling.
