Description
Technical Field
The invention relates to the field of communication devices, in particular to an integrated communication device integrating a coupler and a circulator.
Background
Currently, in the field of communications, a combined device of a coupler and a circulator is commonly used. The circulator is a multi-port device, wherein the transmission of electromagnetic waves can only circulate along a single direction, and taking the circulator with only three ports (port I, port II and port III) as an example, signals can only be transmitted along the direction of the port I → the port III → the port I, and the opposite direction is isolated. In the modern radar and microwave multi-path communication system, a device with a unidirectional ring characteristic is used. For example, a circulator is often used as a duplexer in a radar system in which a transmitting and receiving device shares an antenna. In a microwave multiplex communication system, signals of different frequencies can be separated by a circulator.
The principle of the circulator is still the anisotropic nature of the magnetic field biasing ferrite material. The microwave structure has microstrip type, waveguide type, strip line type and coaxial type, wherein most of microstrip three-terminal circulators are used, ferrite material is used as medium, a conduction band structure is arranged on the microstrip three-terminal circulators, and a constant magnetic field is applied to the microstrip three-terminal circulators, so that the microstrip three-terminal circulators have the circulation characteristic. If the direction of the bias field is changed, the circulating direction changes.
At present, power loss is easily generated in the combined device of the coupler and the circulator, and unnecessary extra loss and cost are generated by constructing a transmission line for connecting (matching) the coupler and the circulator, for example: total reflection loss and insertion loss. Therefore, in order to remove such unnecessary loss and cost, integration and integration of the coupler and the circulator are required.
In view of the above, the present invention provides an integrated communication device integrating a coupler and a circulator.

Rather, modifications and equivalents of the invention are intended to be included within the scope of the claims.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present invention. It will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and components are not shown in detail in order not to obscure the subject matter of the invention.
Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The exemplary embodiments of the present invention are also merely exemplary of a ribbon wire loop former having three ports. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the shape and size may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or similar components.
Fig. 1 is a perspective combination view of a communication device according to a first embodiment of the present invention. Fig. 2 is an exploded perspective view of a communication device according to a first embodiment of the present invention. As shown in fig. 1 and 2, a communication device 1a of a first embodiment of the present invention includes: a ribbon wire circulator 10 and a coupling 11 integrated in the ribbon wire circulator 10. In this embodiment, only one coupling member is integrated in one circulator, but the invention is not limited thereto.
The stripline circulator 10 includes a housing 104 and a housing cover 105. The housing 104 has a circular sidewall 1041 and a rectangular bottom 1042 to form a cylindrical accommodation space 1043 in the housing 104. The cover 105 is detachably screwed with the housing 104 by a screw, covering the accommodation space 1043.
The side wall 1041 of the housing 104 has three opening portions 1044, but not limited thereto. One opening 1044 is provided with a resistor 1045, and the resistance of the resistor 1045 may be, but is not limited to, 50 ohms which is an industry standard.
The stripline circulator 10 further includes a magnetic assembly and a conductive coupling 103 housed in the accommodation space 1043. The magnetic assembly includes a first magnetic assembly 101 and a second magnetic assembly 102, and the first magnetic assembly 101 and the second magnetic assembly 102 are disposed opposite to each other to generate a magnetic field.
In this embodiment, the first magnetic assembly 101 includes a first permanent magnet 1011, a first thermal resistant spacer 1012, and a first ferrite medium 1013 stacked in that order in a direction toward the electrically conductive coupling 103. The second magnetic assembly 102 includes a second ferrite medium 1021, a second heat resistant spacer 1022, and a second permanent magnet 1023 stacked in this order in a direction away from the guide coupler 103 to avoid the up-down description. The first ferrite medium 1013 and the second ferrite medium 1021 together sandwich the coupling element 11 and the conductive coupling element 103. Because the temperature of the stripline circulator 10 is high during operation, the first magnetic component 101 and the second magnetic component 102 inside the stripline circulator must be made of high-temperature-resistant materials. The first thermal barrier layer 1012 and the second thermal barrier layer 1022 may be high temperature resistant conductive metal materials, such as: iron sheet, soft steel sheet, or floppy disk, etc., but not limited thereto. The first magnetic assembly 101 and the second magnetic assembly 102 together form a magnetic field in the accommodating space 1043. The strength of the magnetic field may be specifically altered by replacing the first thermal barrier layer 1012 and the second thermal barrier layer 1022 with different thicknesses. The thicker the thickness of the first thermal barrier layer 1012 and/or the second thermal barrier layer 1022, the weaker the strength of the magnetic field; the thinner the thickness of the first thermal barrier layer 1012 and/or the second thermal barrier layer 1022, the stronger the strength of the magnetic field.
In addition, as an alternative embodiment, in order to prevent the components (the first magnetic assembly 101, the second magnetic assembly 102, the conductive coupling element 103, and the coupling element 11) in the accommodating space 1043 from being shifted when the housing cover 105 is rotated on the housing 104, an anti-rotation positioning plate 106 is disposed between the housing cover 105 and the second magnetic assembly 102. The periphery of the anti-rotation positioning plate 106 has three protrusions 1061 in different directions, and the direction of the protrusions 1061 matches with the direction of the three openings 1044 of the side wall 1041, so that the protrusions 1061 can be positioned and engaged with the three openings 1044 of the side wall 1041. When the housing cover 105 is rotated, the rotation preventing positioning plate 106, which cannot be rotated, blocks the downward transmission of the rotational force of the housing cover 105. It is ensured that the components in the accommodating space 1043 are not displaced. Furthermore, a third thermal resistant spacer 107 may be disposed between the anti-rotation positioning plate 106 and the magnetic assembly 102 to further prevent the rotational force of the housing cover 105 from being transmitted downward.
An electrically conductive link 103 is located between the first magnetic assembly 101 and the second magnetic assembly 102. Fig. 3 is a schematic structural diagram of a coupling element and a conductive coupling element in a communication device according to a first embodiment of the present invention. As shown in fig. 3, the electrically conductive link 103 includes a center conductor 1031 located within the outer periphery of the magnetic assembly and within the magnetic field range, and three wire arms 1032 extending outwardly from the center conductor 1031.
In the present embodiment, the three wiring arms 1032 are evenly distributed in the circumferential direction, that is: the angle between two adjacent wiring arms 1032 is 120 °. The three wiring arms 1032 of the conductive coupler 103 each protrude from the side wall 1041 through the opening 1044. The number of the connection arms 1032 of the conductive couplers 103 matches the number of the openings 1044 of the sidewalls 1041.
Each of the wiring arms 1032 includes: an inductive wire 10321, a contact pad 10322, and at least one capacitor 10323. The inductance line 10321 extends outward from the center conductor 1031, and the inductance line 10321 is coupled to the first coupling portion 111. The contact 10322 has a first end and a second end, the first end of the contact 10322 is connected to the inductor 10321, and the second end extends out of the sidewall 1041 from the opening 1044. For example: each of the wire arms 1032 may have one or two capacitive portions 10323 connected to a first end of the contact pads 10322. The capacitor 10323 of each connecting arm 1032 cooperates with the contact 10322 to engage with the inner side of the opening 1044, so as to position the conductive coupling member 103 more precisely and prevent the conductive coupling member 103 from moving. The conductive coupling element 103 and the coupling element 11 are made of silver-plated copper sheets, but not limited thereto.
Fig. 4 is an enlarged view of the area a in fig. 3. Unlike the prior art, as shown in fig. 4, the coupling element 11 includes a first coupling portion 111 within the magnetic field range and within the outer periphery of the magnetic assemblies 101, 102. The first coupling portion 111 of the present invention is located in the space 110 between the first magnetic assembly 101 and the second magnetic assembly 102, the first coupling portion 111 is opposite to the inductive wire 10321 of the connection arm 1032, and the first coupling portion 111 and the inductive wire 10321 generate a coupling effect under the action of the magnetic field between the first magnetic assembly 101 and the second magnetic assembly 102. Thus, by adding the coupling member 11 in the range of the magnetic field in the stripline circulator 10, not only can a coupler be formed in the stripline circulator 10, but also, thanks to the highly integrated structure, the line between the stripline circulator 10 and the coupler of the present invention is greatly simplified, the loss caused by line connection is greatly reduced, and the total reflection loss and insertion loss in the connected state are also reduced.
The first coupling portion 111 may be close to and parallel to the opposite inductive wire 10321 to obtain the best coupling effect, but not limited thereto. The first coupling portion 111 may be provided in the vicinity of the inductance line 10321 in a substantially parallel direction.
From a spatial perspective, the first coupling portion 111 and the conductive coupling member 103 are located on the same plane between the first magnetic assembly 101 and the second magnetic assembly 102 (as shown in fig. 3). On the basis of the present invention, it also falls within the protection scope of the present invention to adjust the position relationship between the first coupling portion 111 of the coupling element 11 and the conductive connecting element 103 in the magnetic field.
In the present invention, the coupling degree between the first coupling portion 111 and the opposite connection arm 1032 is 10dB to 30dB (decibel), and the coupling degree between the first coupling portion and the opposite connection arm can be changed according to actual needs, but not limited thereto. The coupling effect of the first coupling portion 111 and the inductive wire 10321 can be affected by various factors, such as: the linear distance D between the first coupling portion 111 and the inductance line 10321 is larger, and the closer the linear distance D is, the greater the coupling effect is; the further the straight distance D, the smaller the coupling effect. Or, the larger the width W of the wire body of the inductor 10321, the larger the width W of the inductor 10321, the larger the coupling effect; the smaller the width W of the inductor line 10321, the smaller the coupling effect. The technical scheme of strengthening the coupling effect by changing the parameters on the basis of the invention also falls into the protection scope of the invention.
With continued reference to fig. 2 and 4, coupling element 11 has first and second ends 112 and 113, and first and second ends 112 and 113 of coupling element 11 and opposing wire arm 1032 together extend out of a side wall 1041 in an opening 1044. The first end 112 of the coupling element 11 is perpendicular to the opposing contact 10322, and the second end 113 of the coupling element 11 is parallel to the opposing contact 10322. A first end 112 of the coupling element 11 protruding from the opening 1044 connects the resistor 1045 so that the coupling element 11 forms an embedded directional coupler with an opposing wiring arm 1032 (see fig. 3). Also, during the mounting process, as the housing cover 105 is screwed to the housing 104, the first end 112 of the coupling element 11 directly contacts the resistor 1045, ensuring an electrical connection.
The coupling element 11 may also have a second coupling portion 115 located primarily outside of the magnetic field range, and the second coupling portion 115 may be formed between the second end 113 of the coupling element 11 and the first coupling portion 111. The second coupling portion 115 is located outside the outer periphery of the magnetic assemblies 101 and 102, and the second coupling portion 115 is parallel to and close to the contact piece 10322, and generates a coupling effect with the contact piece 10322 outside the magnetic field, so as to further enhance the overall coupling effect of the coupling element 11. Of course, the coupling effect of the first coupling portion 111 in the magnetic field is much stronger than that of the second coupling portion 115.

Fig. 6 is a schematic structural diagram of a coupling element and a conductive coupling element in a communication device according to a second embodiment of the present invention.

The impedance of the coupling element 11 'can be further changed by changing the length, the reciprocating distance and the like of the reciprocating broken line segment 114, so as to achieve the purpose of enhancing the coupling effect of the coupling element 11' and the inductance line 10321. Other technical features are the same as those in fig. 1 to 4, and are not described herein again.

Fig. 9 is an exploded perspective view of a communication device according to a third embodiment of the present invention. Fig. 10 is a schematic structural diagram of a coupling element and a conductive coupling element in a communication device according to a third embodiment of the present invention. As shown in fig. 8 to 10, unlike the first and second embodiments, in the communication device 1c of the third embodiment of the present invention, the stripline circulator 10 is an isolator. The coupling member 11 in the communication device 1c of the third embodiment is the same as the coupling member 11 in the communication device 1a of the first embodiment. The coupling element 11 and the ribbon circulator 10 form a directional coupler, and the two openings 1044 are respectively provided with resistors, and besides the first end 112 of the coupling element 11 is connected with one of the resistors 1045, one wiring arm 1032 of the conductive coupling element 103 can also be connected with the other resistor 1046, so that the ribbon circulator 10 forms an isolator. Other technical features are the same as those in fig. 1 to 4, and are not described herein again.
Fig. 11 is an exploded perspective view of a communication device according to a fourth embodiment of the present invention. Fig. 12 is a schematic structural diagram of a coupling element and a conductive coupling element in a communication device according to a fourth embodiment of the present invention. As shown in fig. 8 to 12, unlike the first and second embodiments, in the communication device 1d of the fourth embodiment of the present invention, the stripline circulator 10 is an isolator. The coupling piece 11 'in the communication device 1d of the fourth embodiment is the same as the coupling piece 11' in the communication device 1b of the second embodiment. The coupling element 11 'and the ribbon circulator 10 form a directional coupler, and the two openings 1044 are respectively provided with resistors, and besides the first end 112 of the coupling element 11' is connected with one of the resistors 1045, one wiring arm 1032 of the conductive coupling element 103 can also be connected with the other resistor 1046, so that the ribbon circulator 10 forms an isolator. Other technical features are the same as those in fig. 5 to 7, and are not described herein again.
With continued reference to fig. 10, in order to describe the operation principle of the communication device of the present invention, three terminals of the conductive coupling member 103 are set as an E terminal, an F terminal and a G terminal, respectively. The first end 112 of the coupling member 11 is an H-end and the second end 113 is an I-end. Taking the coupling degree of the coupling member 11 and the electrical coupling member 103 as an example of 30dB,
when a current with a power of 100 w flows through the isolator in a forward direction, i.e., from the E terminal of the conductive coupling element 103 to the F terminal, the first coupling portion 111 of the coupling element 11 is coupled with the inductance line 10321 of the conductive coupling element 103, and the H terminal of the coupling element 11 obtains a power of about 0.1 w, and when the isolation is 30dB, the I terminal also obtains a power of about 0.1 w. When the current passes through terminal E to terminal F, a portion of the power is absorbed by the material of the conductive link 103, and then a power of 90 watts is substantially maintained.
When a current reversely flows through the isolator, that is, when the current flows from the terminal F to the terminal E of the conductive connecting element 103, a part of the power current flows to the terminal G of the conductive connecting element 103 and is absorbed by the resistor 1046 at the terminal G, and the other small part of the power current flows to the terminal E and is coupled by the first coupling part 111 of the coupling element 11, and if the terminal H and the terminal I of the coupling element 11 respectively obtain the coupled current, the resistor 1045 at the terminal I further continuously absorbs the power of the reverse current.
In summary, the communication device of the present invention can spatially integrate the coupler and the circulator together, and reduce the total reflection loss and insertion loss in the connected state.
The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalent substitutions or equivalent transformations fall within the scope of the present invention.
