Abstract: A driver for a ferrite load includes a controller, a clock generator, and a pulse generator. The driver includes a first driver element coupled to the pulse generator and configured to provide a first pulse with a first width that drives a current in a first direction through the load for setting a first magnetic flux. The driver includes a second driver element coupled to the pulse generator and configured to provide a second pulse, having a second width that is independent of the first width, that drives a current in a second, opposite direction through the load for setting a second magnetic flux. The driver includes a feedback input that is configured to receive at least one signal used by the controller to selectively cause the pulse generator to activate one of the first and second driver elements to apply a first or second pulse, respectively, to the load.

Abstract: Disclosed is a method and an apparatus enabling operation of balanced phase shifts providing uniformity that the insertion loss do not show variation with the derived angles in phase shift. The invention incorporates a resonator supporting nonreciprocal wave propagation. The resonator is divided in two equal parts showing symmetry so that the change in electronic parameters from one part of the resonator counter balances the other part, thereby causing no change to the resonance condition. Amplifiers are thus not needed by the phase-shift operation. Electronically active materials, such as ferrites, ferroelectrics, and/or varactors, are utilized, and the phase shifter device can be fabricated assuming a variety of transmission-line geometries, such as microstrips, striplines, waveguides, coax lines, parallel wires, coplanar waveguides, image lines, fin lines, and slot lines, providing versatility and convenience in applications.

Abstract: Methods and devices for accelerating or delaying an electromagnetic signal. A rectangular waveguide phase shifter has a ferrite filled center section with a pair of magnetic bias lines placed on opposing sides of the waveguide, each bias line being adjacent to one of the two opposing sides. Each magnetic bias line creates a magnetic field in the ferrite filled center section. The resulting magnetic field in half of the center section has the same magnitude but is oppositely directed to the magnetic field in the other half of the center section. This ideally results in a zero magnetic field at the very center of the ferrite filled center section. A microwave signal propagates through the waveguide phase shifter in a direction perpendicular to the magnetic field lines. The amount of phase shift provided depends on the magnitude of the magnetic fields. These magnetic fields are controllable by adjusting the current passing through the bias lines.

Abstract: A dielectric waveguide reciprocal ferrite phase shifter is provided for usen a dielectric waveguide transmission line. The phase shifter is comprised of a length of ferrite of the same cross-sectional dimension as that of the dielectric waveguide and in fact becomes a section of the transmission line. The length of ferrite bears a thin plastic layer on its top and bottom surface and metal plates on each piece of plastic. The length of this multilayer structure then has a wire coil wrapped around in order to provide a d.c. magnetic biasing field along the length of the ferrite thereby enabling magnetization of the ferrite resulting in a reciprocal phase shift or change in electrical length within the structure.
