Description
Technical field
It the utility model is related to a kind of micro-strip ferrite circulator structure.
Background technology
Ferrite is that one kind has ferromagnetic metal oxide.For electrical characteristics, ferritic resistivity ratio metal,
Alloy magnetic material is much bigger, and also has higher dielectric properties.Have when ferritic magnetic property is also manifested by high frequency compared with
High magnetic conductivity.Thus, ferrite has become the widely used nonmetal magnetic material in high frequency light current field.Due to ferrite list
The magnetic energy stored in the volume of position is relatively low, and satisfying, it is relatively low to close the intensity of magnetization（Usually there was only the 1/3~1/5 of pure iron）, thus limit
It is in the low frequency forceful electric power of more demanding magnetic energy density and the application in high-power field.
Waveguide junction circulator is mainly used in radar emission receiver, and waveguide junction circulator is in receiver, transmitter and antenna
Between play transmitting-receiving transformation, the signal of transmitter is transferred to antenna by waveguide junction circulator and is launched away, reflects at the same time
The signal returned is received by the same antenna, is transferred to through waveguide junction circulator in reception system.Waveguide junction circulator is in systems, main anti-
The power that only antenna mismatch is reflected back is damaged caused by power source, plays a part of protecting power source.
With the development that complete machine is equipped, the requirement of higher is proposed to microwave device, such as wants cube smaller, thickness more
It is thin, bandwidth is wider etc..Minimized to realize, generally use microstrip ferrite structure.Generally adopted between microwave device and installation base plate
With the mounting means of gold wire bonding.Bad situation is matched since microwave device and subscriber connection easily produce, it is often necessary to
User adds metal strip to be matched in connectivity port, and use is very inconvenient.
Utility model content
The purpose of the utility model is to overcome the shortcomings that the prior art, there is provided one kind miniaturization, easy to use, matching
The good micro-strip ferrite circulator structure of energy.
The purpose of this utility model is achieved through the following technical solutions：A kind of micro-strip ferrite circulator structure, it is wrapped

Separate and be equipped with P1 ports, P2 ports and P3 ports, P1 ports and P2 ports, P3 ports communicate, and P1 ports are input port, P2
Port and P3 ports are output port, and each port includes port pins, are equipped with left and right sides of each port
With dot, match and connected between dot and port pins by gold wire bonding.
Further, the quantity of the matching dot and spun gold is configured according to actual needs.
Further, the lower surface of the gyromagnet substrate and the upper surface of bottom plate overlap.
Further, between the rare-earth magnet and temperature-compensating plate it is full fitting installation.
The utility model has the following advantages：A kind of micro-strip ferrite circulator structure described in the utility model has small
Type, it is easy to use, matching performance is good the characteristics of, for realize minimize, generally use microstrip ferrite structure, ring-shaped device with
The mounting means of gold wire bonding is generally used between installation base plate, meanwhile, in order to facilitate the matching between user's substrate and belt device,
Using 1 matching dot is respectively added on output, input terminal lead both sides, when in use, matching dot and port are drawn by user
Connected between line by gold wire bonding, bonding gold wire quantity and bonding matching dot number are selected according to actual conditions, so that
