Abstract
Reciprocal and locked digital ferrite phase shifter is to change the microwave transmission device that inserts phase shift.To parallel E face in the known rectangular waveguide and along transmitting the structure that the ripple direction is arranged some rectangle magnet rings (2), the method that the present invention proposes widening frequency band, minimizing standing-wave ratio is as follows: replace nonmagnetic substance to do the partition (4) that separates magnet ring (2) with magnetic material, demagnetization lead (5) is placed on partition (4) and opens in the demagnetization groove (6) near the side of magnet ring (2).In addition, magnet ring (2) is kept at a distance the raising figure of merit with waveguide (1) two broadside; Magnet ring can be combined into to improve temperature stability in segmentation.
Description
Reciprocal and locked digital ferrite phase shifter is to change the microwave transmission device that inserts phase shift.
No. 3355683 patent of the U.S. announced a kind of reciprocal and locked digital ferrite phase shifter.This phase shifter is by being parallel to the E place in the middle of the broadside and arrange several rectangle magnet rings along the electromagnetic transmission direction and constitute in the rectangular waveguide, each magnet ring all is to insert the non-magnetic media partition between a phase-shifting unit and the magnet ring to eliminate the influence of magnetizing field to each other.On the ring body of magnet ring, have one in addition and penetrate the aperture that the demagnetization lead is used.
The shortcoming of said structure is in order to reduce the bandwidth of standing-wave ratio, increase device, to require the approaching as far as possible nonmagnetic substance of the selection and the dielectric constant of magnet ring material to do partition.Simultaneously, and have aperture, make the figure of merit decrease because ring body and waveguide broadside join.
For addressing the above problem, the present invention proposes to use the magnetic material identical with magnet ring to do partition, and makes ring body and Guide of Wide Wall keep the method for certain distance.At this moment the lead that demagnetizes passes between partition and magnet ring, constitute the required magnetic circuit of demagnetization jointly by partition and magnetic ring body, and the magnetizing field of using the non-magnetic media sheet thinner than partition to isolate to avoid demagnetizing between partition and magnet ring locks, and weakens the influence of the magnetizing field between magnet ring and the magnetic partition.In addition, can also be on ring body cracking perpendicular to the magnetizing field direction makes material can not enter the magnetic saturation state, thereby helps improving the device temperature performance.
As one embodiment of the present of invention, the drawn solid of this phase shifter of figure one adds phantom.The magnet ring of placing in the rectangular waveguide (1) (2) is to be linked as integral body by bonding up and down non-magnetic media sheet (3) and waveguide (1).Magnetic partition (4) uses the materials processing with the magnet ring homogenous materials to form, and waist has the demagnetization groove (6) of placing demagnetization lead (5) usefulness along the H field direction among its close side of magnet ring (2), uses the non-magnetic media sheet (7) than partition (4) Bao Deduo to separate between magnetic partition (4) and the magnet ring (2).(8) are the magnetization leads among the figure.
Do experiment in five superhigh frequency bands and show thickness I when partition (4) (ε=16.5)
1Be 3 millimeters, non-magnetic sheet (7) (ε=4) I
2When being 0.08 millimeter, the standing-wave ratio of four bit phase shifter made from the inventive method is less than 1.2, and bandwidth is greater than 25%.And owing to removed the demagnetization hole, the processing technology of ferrite core has also become simply.Simultaneously, replace nonmagnetic substance to do the performance that partition has not only improved device,,, reduced cost so solved the difficulty of the approaching nonmagnetic substance of searching and magnet ring material ε also because the magnetic partition adopts the magnet ring of scrapping to process usually with magnetic material.This replacement also makes the impedance that distributes along the electromagnetic transmission direction in the phase shifter become evenly, thereby has also comparatively made things convenient for aspect assembling and setting.
In the occasion that requires higher temperature stability, magnet ring (2) can be combined in segmentation, utilizes slit between each section to cause approximately to make demagnetizing factor to remain on effect about 0.15.
Claims (5)
1, reciprocal and locked digital ferrite phase shifter is to change the microwave transmission device that inserts phase shift, it is arranged several along the electromagnetic transmission direction by parallel E place in the rectangular waveguide and does the magnet ring that phase-shifting unit uses and forms in the middle of wide wall, and between the magnet ring insertion partition to eliminate the influence of magnetizing field to each other.Feature of the present invention is that the partition (4) that inserts between magnet ring (2) is used with the magnet ring identical materials and made, and uses the non-magnetic media thin slice (7) littler than the thickness of partition (4) to separate between partition (4) and magnet ring again.
