Abstract : The construction and operation of a 10-channel filter bank, operating at X-band and relying on magnetostatic wave (MSW) propagation in epitaxial yttrium iron garnet (YIG) films is described. Two filter techniques were investigated. First, reflctive arrays were examined for their use in this application, but it was concluded that this technique was insufficiently developed at this time. The second technique used ten stagger-tuned narrow band magnetostatic forward volume wave (MFVW) delay lines fed from a common input transducer with separate outputs. This approach yielded characteristics which approximated the device objectives.
