The axis of the permanent magnet (1), the axis of the ceramic chip (2), and the axis of a disk of the microstrip circuit (3) are overlapped. The lower surface of the microwave ferrite substrate (4) is welded on a magnetic metal base (5) through soldering paste. The microstrip circulator is small in volume, light in weight, simple in structure, convenient in use, excellent in performance, and is suitable to be used for the surface mounting technology, and is easy for integration of microwave circuits.
Description
Technical field:
The utility model relates to circulator technical field, is specifically related to a kind of microstrip circulator.
Background technology:
Circulator, is a kind ofly will to enter the incident wave of its arbitrary port, imports the multiport device of next port according to the direction order of being determined by quiet bias field into.
Existing embedded circulator structure, does shell with discrete permeability magnetic material, and the surrounding of cavity is glued together permeability magnetic material with adhesive.In cavity, pack successively microwave ferrite sheet (not being with ceramic ring medium), center conductor into, microwave ferrite sheet, magnetic conduction disk, magnetic conduction disk, temperature-compensating sheet and permanent magnet, upper and lower both sides are respectively two permeability magnetic materials, and it is screwed respectively in cavity upper and lower surface.Permanent magnet provides bias magnetic field for ferrite, and center conductor has three to draw end points, is introduced to respectively outside three ports of cavity; This structure is fixed on cavity with adhesive and screw by polylith permeability magnetic material, forms magnetic loop with cavity.
Above-mentioned this structure exists processing consumptive material large, and magnetic circuit is not exclusively closed, and leakage field is larger, and magnetic circuit efficiency is low, the defect of device temperature poor-performing, and whole device volume is excessive.Simultaneously along with the development of electronic technology, more and more higher to the requirement of circulator miniaturization.
