  • Patent number: 4780667
    Abstract: A discriminator having a power divider that divides a signal under test into a signal channel component and a reference channel component. A tunable delay line, such as a magnetostatic wave delay line, inserts a delay into the reference channel. A multielement input transducer selects a narrow band of spin wave wavelengths that are activated, thereby producing frequency discrimination. A phase detector is responsive to both channels to produce an output signal to a spectrum analyzer. A feedback loop, responsive to the output signal of the phase detector automatically places these two components into a quadrature relationship. The discriminator is automatically calibrated by tuning the delay line to values away from the quadrature condition in order to determine the discriminator consant.

  • Patent number: 4774483
    Abstract: A magnetostatic wave resonator having a transducer oriented such that it is tangent at all points to a wavefront of a traveling wave component of a resonant mode of the resonant cavity. In a rectangular cavity of width L.sub.x and length L.sub.y, the transducer is perpendicular to the wavevector k=(m.pi./L.sub.x)e.sub.x +(n.pi./L.sub.y)e.sub.y for some nonzero integers m and n, whereby the transducer optimally transfers energy into the resonant mode that is a linear superposition of travelling waves that includes this wavevector. This enhances coupling into the resonant mode of interest and reduces the amount of coupling into spurious modes.

  • Patent number: 4652338
    Abstract: In a batch process of manufacturing magnetostatic resonators, photolithographically etching a ferrimagnetic layer, that has been deposited on a dielectric substrate, to produce a plurality of disjoint blocks of ferrimagnetic material. Each block has a pair of sides that are substantially parallel for use in reflecting magnetostatic waves to form a resonator. A conductive layer is deposited on the wafer and then this layer is photolithographically etched to form a transducer adjacent to each of these reflecting sides.
