Dual-Mode Ferrite Phase Shifters

The MAG dual-mode phase shifter is the only reciprocal latching, ferrite phase shifter that has been made in large quantity. This phase shifter uses a quadrantally symmetric ferrite rod which is metallized to form a ferrite-filled waveguide. The cross section must have quadrantal symmetry so that circularly polarized energy will propagate through it without change of field distribution. The name "dual-mode" comes from the fact that the structure must support two orthogonal, linearly polarized modes for proper operation.

Electronic Drivers for Dual-Mode Ferrite Phase Shifters

Most ferrite phase shifters are constructed from a continuous section of ferrite with the phase shift quantization, frequency compensation and temperature compensation allocated to the electronic driver. The driver accomplishes these tasks by operating the ferrite in a partially magnetized state. As the magnetization varies from negative saturation to positive saturation, the relative saturation of the ferrite is controlled by adjusting the magnetic flux density in the ferrite core.

Rotary-Field Ferrite Phase Shifters

MAG analog rotary-field ferrite phase shifters are uniquely designed to provide an unlimited phase shift with modulo-360 degree phase control characteristics that are independent of frequency, temperature, power level, and ferrite material parameters.

Toroid Phase Shifters

MAG continues to broaden its product line with the addition of toroidal phase shifters. These units provide good VSWR, low insertion loss, and minimal insertion phase variation.

Synthetic Aperture Radar Components

Synthetic Aperture Radars provide extremely high resolution imagery from long ranges in all types of weather, day or night. Microwave Applications Group (MAG) provides components for several well-known Synthetic Aperture Radar systems. Among these components are MAG’s Rotary-Field Phase Shifters and MAG’s low-cost Dual-Mode Phase Shifters.

Latching Rotary-Field Phase Shifters

MAG’s Latching Rotary-Field Ferrite Phase Shifters combine the best of phase shifter technologies. Latching Rotary-Field Ferrite Phase Shifters offer true modulo-360 degree operation with excellent peak and average power handling capabilities across a 1 GHz bandwidth at X-Band. The Latching characteristic eliminates the need for holding current thereby reducing system power needs.
