Abstract: A group delay equaliser for a repeater in a waveguide communication system uses a magnetostatic wave delay line as a dispersive element to compensate for inherent dispersion in the waveguide. The delay line uses a thin ferrimagnetic film in which a propagation path is defined which is biased by a uniform adjustable magnetic field which is established to provide an adjustable dispersion characteristic. The film has associated with it means for preventing reflections of magnetostatic waves propagated beyond the ends of the propagation path. A substantially linear propagation delay with frequency is achieved over a bandwidth of 500 MHz. at a centre frequency of 1.5 GHz.

Abstract: A frequency selective limiter operative in a magnetostatic surface mode with a pair of parallel microstrip transducers formed on a substrate and having a length at least equal to the width of an overlaying YIG film ranging in thickness from about 0.1 μm and about 5.0 μm and having a width equal to or less than about 20. mm and which is biased by a permanent magnetic field applied in the plane of the film parallel to the transducers so that magnetostatic surface waves propagate therebetween in the YIG film so as to provide a limiter threshold level in the range of −75 dBm to −35 dBm. The transducers have specific spacings and dimensions.
