Abstract
The reciprocal transverse-field ferrite phase-shifter that uses in the microwave transmission is specially adapted to the short range phased array radar.Make simple and reduce cost with making it for the speed that improves control phase, the present invention proposes with the cross magnetization field as middle jayrator.Both sides then constitute a complete reciprocal transverse-field ferrite phase-shifter with 45 ° of fixing nonreciprocal polarization rotators.
Description
The reciprocal transverse-field ferrite phase-shifter that uses in the microwave transmission is specially adapted to the short range phased array radar.The described dual-mode reciprocal phase shifter of known document (1) is formed by three sections: phase shift usefulness is made for longitudinal magnetization field section in the centre, and both sides are nonreciprocal polarization devices of four magnetic poles of fixing, belongs to cross magnetization field section.Change-over time was greater than 20 microseconds when this device was worked in the centimeter wave frequency range.
For improving conversion speed, the present invention proposes to change interlude into cross magnetization field section, and both sides then are longitudinal magnetization field section.Its mode of operation is selected like this: the cross magnetization field in this plane each other on two directions of quadrature respectively two electromagnetic waves to mutual reverse transfer equal phase shift is arranged, the effect of longitudinal polarization field is to make 45 ° of the polarization of ele direction of transmission rotations.
As the embodiment that the present invention suggested plans, cross magnetization field section can realize with locking-type four magnetic pole jayrators, and longitudinal magnetization field section can be that 45 ° Faraday rotator is realized with the anglec of rotation.
Figure one is that locking-type four magnetic pole jayrators are at the profile perpendicular to the electromagnetic transmission direction.With square ferrite bar (1) with its side metalization to form waveguide (2), respectively establish a yoke (4) respectively at the middle position of four sides, the coil (5) on yoke passes to exciting curent.Dotted line represents to require the magnetic line of force in formed magnetic field in the ferrite bar among the figure.
Experiment shows, can accomplish below 10 microseconds change-over time of this phase shifter.Because electromagnetic wave all transmits in the linear polarization mode in whole phase shifter, rather than resemble and to become the circularly polarised mode at interlude the dual-mode reciprocal phase shifter, comparatively made things convenient for so debugging also becomes.
If a Faraday rotator of above-mentioned reciprocal transverse-field ferrite phase-shifter is changed to orthomode coupler, just formed duplexing reciprocal transverse-field ferrite phase-shifter, the duplexing reciprocity phase shifter that it is introduced than document (2) is much structurally simple.
