Abstract
The invention discloses a kind of broad frequency micro-band circulator, belong to microwave device technology field.The present invention includes ferrite ceramics substrate, microstrip line, ferrite and Y types loading minor matters, and circular central knot point is provided with ferrite ceramics substrate, and additional three Y types loading minor matters carry out broadband.The present invention can caused by beneficial effect be in (6Hz 9.5Hz).This circulator has miniaturization, broadband and low-loss feature.
Description
Technical field
The present invention relates to microwave technical field, and in particular to a kind of broad frequency micro-band circulator.
Background technology
Mid-twentieth century, brought using microwave circulators made of ferritic gyromagnetic effect to microwave technology great
Breakthrough and development.In World War II, microwave ferrite begins to solve a series of problem, such as solves
Determined radar equipment anode-cathode distance and antenna duplexer the problems such as, and as one of critical component of military radar system.With
, microwave ferrite technology develops rapidly, and microwave ferrite technology has moved towards civilian since military, circulator extensive use
In fields such as space technology, commercial communication, medical treatment.In various fields, microwave ferrite all plays very big effect, microwave iron
The market of oxysome is increasing.
Microwave circulators are that one kind can be unidirectional using magnetic field bias Ferrite Material anisotropic properties progress electromagnetic wave
The part of annular delivery, unidirectional loop device all act on substantially in modern age radar and micro multi-channel communication system.We can profit
Multifrequency signal is separated with circulator.
Compared to existing ferrite micro-strip circulator, what the present invention designed has obvious excellent in terms of performance and miniaturization
Gesture, and contribute to the production of large-scale.
The content of the invention
Goal of the invention：A kind of micro-strip circulator is provided, wherein carrying out broadband using Y types minor matters.Y types minor matters make in circulator
Microstrip line has low characteristic impedance, while the line of rabbet joint has higher characteristic impedance.
In order to solve the problems existing in background technology, the present invention is to adopt the following technical scheme that：A kind of ferrite wideband
Micro-strip circulator, including ferrite ceramics substrate, microstrip line, ferrite centre junction and Y types loading minor matters.Made pottery in ferrite
It is carved with microstrip circuit on the front of ceramic chip, ferrite ceramics substrate side is by provided with by the patch of front microstrip circuit mouth and the back side
The micro-strip mouth that welding equipment disk is turned on.There are Y type minor matters to make microstrip line that there is low characteristic impedance on the ferrite, while the line of rabbet joint has
There is higher characteristic impedance, band-pass behavior can be improved.The pad that the ferrite back side is set forms isolated area, its technique with base
Simplicity, it is easily formed.As a kind of new technical scheme, front microstrip circuit will be connected by 3 sides metallization micro-strip mouths
Connect the attachment pad at 3 back side.
The present invention has following beneficial effect to be：Miniaturization, broadband, low-loss, superior performance is simple in construction, reliably
Property strong, the advantages that thermal diffusivity is high and service life is long.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
As shown in figure 1, a kind of ferrite micro-strip circulator, including ferrite ceramics substrate (1), ferrite ceramics substrate
(1) front is provided with (3) (6) (8) micro-strip mouth circuit, and micro-strip mouth circuit is electroplated on ferrite substrate by photoetching technique, ceramics
Substrate is by resinoid bond on microstrip circuit.The ferrite ceramics substrate (1) will overleaf be provided with metal pattern layer and figure
Shape base (because its thickness is extremely low so having display only in figure), ferrite are provided with 3 Y types minor matters and carry out broadband, iron oxygen
Body ceramic substrate side is provided with 3 microstrip circuit mouths.
Ferrite toroidal device insertion loss of the present invention is less than 0.5dB, and reverse isolation degree is more than 20dB, and reflection coefficient of port loss is big
In 15dB, working frequency shows its superior performance in 6Hz-9.5Hz, shows its good broadband ability, and the present invention has
High reliability and stability.
Described above is presently preferred embodiments of the present invention, and without the limitation present invention, all principles and spirit in the present invention
Within, the modification and improvement done are all within the scope of the present invention.
