Abstract
The utility model relates to a kind of microwave passive component, is specially waveguide junction circulator, comprises three the wide arms of waveguide, permanent magnet and ferrites; Three described waveguides wide arm composition Y shape, inside, junction is wave-guide cavity wave, one piece of ferrite is had up and down respectively in wave-guide cavity wave, two pieces of described ferrites are mounted opposite, ferrite opposite side is connected to that center is barren leads knot, barren the leading of described ferrite and center is tied by Boards wall in match block, and match block is arranged in wave-guide cavity wave by adjustment screw; The described upper and lower both sides of wave-guide cavity wave outer wall are separately installed with impedance interchanger, and permanent magnet is arranged on one of them impedance interchanger.The waveguide junction circulator that the utility model provides carries out mounting and adjusting by regulating match block, shortens the debug time of circulator, and loss is lowered in the barren effect leading knot in center, and impedance interchanger improves resistance capabilities.
Description
Technical field
The utility model relates to a kind of microwave passive component, is specially waveguide junction circulator.
Background technology
Waveguide junction circulator a kind ofly realizes the unidirectional belt multiport Microwave Iron Oxide Elements of microwave signal; utilize the gyromagnetic effect that Ferrite Material produces under the effect of applying dc magnetic field; make the deflection of the microwave generation certain angle of incident circulator, realize the duplex of microwave network, decoupling, protection and matching feature.Waveguide junction circulator is mainly used in radar antenna feed system, play a part in antenna transmission-receiving system coupling, go in ring, duplexing.Existing waveguide junction circulator loss is high, broadband is little, and the scale error that ferrite produces in the course of processing, and by installation process medial error, cause impedance not reach and mate completely.
Utility model content
For above-mentioned technical problem, the utility model provides the waveguide junction circulator of low, the easy adjustment of a kind of loss, and concrete technical scheme is:
Waveguide junction circulator, comprises three the wide arms of waveguide, permanent magnet and ferrites; Three described waveguides wide arm composition Y shape, inside, junction is wave-guide cavity wave, one piece of ferrite is had up and down respectively in wave-guide cavity wave, two pieces of described ferrites are mounted opposite, ferrite opposite side is connected to that center is barren leads knot, barren the leading of described ferrite and center is tied by Boards wall in match block, and match block is arranged in wave-guide cavity wave by adjustment screw; The described upper and lower both sides of wave-guide cavity wave outer wall are separately installed with impedance interchanger, and permanent magnet is arranged on one of them impedance interchanger.
The waveguide junction circulator that the utility model provides carries out mounting and adjusting by regulating match block, shortens the debug time of circulator, and loss is lowered in the barren effect leading knot in center, and impedance interchanger improves resistance capabilities.
