As shown in Figure 1, the four ports of the directional coupler include a common end, a main circuit end, a secondary circuit end and an isolation end, where the isolation end is inside the product and is not reflected externally.

Detailed ways

The technical solutions in the present application will be described below with reference to the accompanying drawings, taking the communication device as a directional coupler.

A directional coupler is a passive microwave device that can be used for power distribution or power combining of signals. The four ports of the directional coupler include a common terminal, a main circuit terminal, a secondary circuit terminal and an isolated terminal.

As shown in FIG. 2, in the microwave transmission system, the common end of the directional coupler 202 is connected to the antenna 201, the main end is connected to the first outdoor unit (ODU) 203, and the secondary end is connected to the second outdoor unit The unit 204 is connected, and the internal isolation terminal is connected with the matched load. The radio frequency signal of the first ODU 203 and the radio frequency signal of the second ODU 204 are combined by the directional coupler 202 to a common terminal for output, and then the antenna 201 converts the radio frequency signal output from the common terminal into electromagnetic waves, which are radiated into the air. Alternatively, the electromagnetic wave is received by the antenna 201 and converted into a radio frequency signal, and the radio frequency signal is input through the common terminal of the directional coupler 202, and then branched to the main circuit terminal and the auxiliary circuit terminal, and the branched radio frequency signals are respectively output to The first ODU 203 and the second ODU 204.

The directional coupler can be divided into two types: balanced and unbalanced according to the energy ratio of the signal from the main circuit end and the secondary circuit end to the common end respectively. The energy ratio X from the terminal to the common terminal is equal, and the energy ratio X of the signal from the main circuit terminal and the secondary circuit terminal to the common terminal in an unbalanced directional coupler is not equal. The conversion relationship between the energy ratio X and the coupling amount Y (unit is dB) is as follows:

Y=20*log(X)dB

Hereinafter, the specifications of the two directional couplers shown in FIG. 3 will be described in detail in the scenario of power combination, taking the coupling amount of the unbalanced specification as 6 dB as an example.

In a balanced directional coupler, the energy ratio of the signal from the main terminal and the auxiliary terminal to the common terminal is equal, that is, the energy ratio of the signal from the main terminal and the auxiliary terminal to the common terminal is 1/2. The energy of the corresponding signal from the secondary end to the common end is -3dB, and the energy of the corresponding signal from the main end to the common end is also -3dB. The above-mentioned balanced coupler is usually used in a scenario where two ODUs work at different frequencies at the same time, also known as a "2+0" scenario, which can double the system capacity compared to using only one ODU;

In an unbalanced directional coupler, the energy ratio of the signal from the main circuit terminal and the secondary circuit terminal to the common terminal is not equal. For example, the energy ratio of the signal from the secondary circuit terminal to the common terminal is 1/4. At this time, the corresponding signal The energy from the secondary end to the common end is -6dB, the energy ratio of the signal from the main end to the common end is 3/4, and the corresponding signal energy from the main end to the common end is -1.3dB. The above-mentioned unbalanced couplers are usually used in a scenario where one ODU works and the other ODU is used as a backup, also known as a "1+1" hot standby (HSB) scenario. In this scenario, if the working ODU In case of failure, it can be switched to the backup ODU to ensure the normal operation of the system.

As shown in Figure 4, the commonly used coupling structures of directional couplers include broadside coupling structure, narrowside coupling structure and magic T structure.

The wide-side coupling structure and the narrow-side coupling structure mainly adjust the coupling amount by adjusting the number, size and distance of the coupling windows. Under this coupling structure, each coupling window will couple a part of the energy of the common end to the secondary end and the isolated end. According to the porous coupling theory, by adjusting the distance between the coupling windows, the energy of each coupling window is superimposed at the secondary end, Cancellation at the isolation end, wherein part of the energy is coupled to the output of the secondary circuit end, and part of the uncoupled energy is output from the main circuit end. Although the coupling amount of the wide-side coupling structure and the narrow-side coupling structure coupler can be adjusted theoretically, the coupling amount of the directional coupler of the structure can be adjusted by adjusting the number, size and distance of the coupling window in practical operation. is more complex and difficult to implement. However, the coupling amount of the coupler with the magic T structure is fixed and not adjustable, and can only achieve 3dB balanced coupling, but cannot realize unbalanced coupling.

In addition, the coupling amount corresponding to the broad-side coupling structure and the narrow-side coupling structure is related to the frequency, so the coupling amount will fluctuate to a certain extent in the working frequency range, which is not stable enough. Moreover, the operating frequency ranges of the broad-side coupling structure and the narrow-side coupling structure are also narrow.

In view of the deficiencies in the prior art, an embodiment of the present application proposes a communication device, which can be used for power distribution or power combination of signals. The coupling amount of the communication device can be adjusted, and the adjustment of the coupling amount does not involve the coupling window. , so it is not affected by the frequency change, the coupling quantity of the communication device is more flat in the passband, and the working frequency range of the communication device can reach wideband or even ultra-wideband. The present application mainly solves the problems that the current directional coupler has a narrow bandwidth, there is a certain fluctuation in the band, and the balanced coupler and the unbalanced coupler cannot be normalized.

Similarly, The second coupling body and the fourth port, the fifth port, and the sixth port can also be connected in other ways. For example, the fifth port and the sixth port can be installed on other surfaces of the second coupling body. Different ports in this application The adjustment principle of the coupling amount corresponding to the installation method is similar, which is not limited in this application.

It should be understood that the naming of the components in the communication device in this application, such as the orthogonal unit, the first main body, the second main body, the common terminal, the isolation terminal, the main circuit terminal, the secondary circuit terminal, etc., are only used as examples. Use other names instead, for example, the first body can also be called the first coupling body, the first orthogonal mode coupling body, the first orthogonal mode coupling core, etc., as long as the same or similar functions can be achieved, this The application is not limited here.

It should be noted that the planes where the quadrature signals after the fourth and fifth processing above are located are perpendicular to the signal transmission direction (ie, the first direction) between the two quadrature units. In the initial state, the first clamp The angle is 0deg. At this time, the direction of the quadrature signal after the fourth processing by the second quadrature unit and the fifth processing by the first quadrature unit is the same.

In a possible implementation manner, the first orthogonal unit is an orthogonal mode coupler (orth-mode transducer, OMT), and/or the second orthogonal unit is an orthogonal mode coupler OMT, and the orthogonal mode The function of the coupler OMT is to separate a signal into two orthogonally polarized signals or to combine two orthogonally polarized signals into one signal, and the orthogonal signals at the two branch ports of the orthogonal mode coupler are isolated from each other. , after being transmitted to the common terminal, they are still orthogonal to each other and do not affect each other.

It should be understood that the orthogonal mode coupler OMT may include narrowband OMT, wideband OMT and ultra-wideband OMT according to the operating frequency range. The relative bandwidth of narrowband OMT is usually less than 10%, the relative bandwidth of wideband OMT is usually greater than 20%, and the relative bandwidth of ultra-wideband OMT is usually greater than 35%, which is the ratio of signal bandwidth to center frequency.

The communication device in the present application realizes the adjustment of different coupling amounts by internally docking two orthogonal units and adjusting the relative angle between the two orthogonal units, that is, the first angle. Next, the adjustment method of the coupling amount of the communication device of the present application in the scenario of power combination will be introduced in detail, that is, the contents of the above-mentioned first processing, second processing and third processing will be further introduced.

FIG. 7 shows a possible coupling amount adjustment method of the communication device in the present application. In the scenario of power combination, it is assumed that the signal input from the first port into the first coupling body is the first signal, and the signal from the second port is assumed to be the first signal. The signal input by the port into the first coupling body is the second signal. After the above-mentioned first processing, the third port outputs the first signal after the first processing, that is, the signal A (that is, the third signal), and the output The second signal after the first processing, that is, the signal B (that is, the fourth signal), the signal A and the signal B are input to the second main body through the fourth port, and the second processing is performed on the signal A to obtain the first component Asinθ and the second component Acosθ, and perform third processing on the signal B to obtain the third component Bcosθ and the fourth component Bsinθ.

By adjusting the relative angle between the two orthogonal units, the angle between the electric field directions between the first port and the fifth port in FIG. 7 can be controlled, that is, the first angle θ. The electric field directions of the port and the sixth port are decomposed, the signal parallel to the electric field of the fifth port enters the fifth port, and the signal entering the fifth port is Acosθ; the signal parallel to the electric field of the sixth port enters the isolation end and enters the The signal at the sixth port is Asinθ.

In the same way, the signal B input from the fourth port is decomposed according to the electric field directions of the fifth port and the sixth port. The signal parallel to the electric field of the fifth port enters the fifth port, and the signal entering the fifth port is Bsinθ; parallel The signal of the electric field at the sixth port enters the sixth port, and the signal entering the sixth port is Bcosθ.

From the analysis in Figure 7, it can be seen that the signals entering the common port #3 port from the main circuit end and the secondary circuit end are Acosθ and Bsinθ, and the signals entering the isolation end are Asinθ and Bcosθ. The ratio of the final output signal from the channel end and the secondary channel end to the common terminal #3 is only related to the first angle θ, and has nothing to do with the frequency, that is, the coupling amount of the signal from the main channel end and the secondary channel end to the common terminal #3 is only related to the frequency. The first included angle θ is related, independent of frequency. That is to say, it is only necessary to adjust the size of the first included angle θ to adjust the coupling amount of the signal from the main circuit end and the secondary circuit end to the common terminal #3 respectively.

According to the above analysis conclusion, the size of the first included angle θ can be adjusted by rotating the unit, so as to adjust the size of the energy ratio, that is, the size of the coupling amount. The corresponding relationship between the included angle θ, the energy ratio, and the coupling amount is as follows:

Table 1

	能量比例energy ratio	耦合量(dB)Coupling amount (dB)
主路端进入到公共端#3Main road end goes to common end #3	cosθcosθ	20log(cosθ)20log(cosθ)
副路端进入到公共端#3The secondary road end goes to the common end #3	sinθsinθ	20log(sinθ)20log(sinθ)

It can be seen from the above correspondence that for a balanced communication device, that is, a communication device with an energy ratio of 1/2 and a coupling amount of 3dB, the corresponding angle θ is 45deg; for an unbalanced communication device, the coupling amount is 6dB as For example, the corresponding angle θ at this time is 30deg. Therefore, the communication device of the present application can realize the conversion between the balanced type and the unbalanced type by adjusting the size of the included angle θ, that is, the communication device of the balanced type and the unbalanced type can realize the normalization.

The adjustment method of the coupling amount of the communication device of the present application in the scenario of power distribution is similar to the adjustment method of the coupling amount of the communication device of the present application in the scenario of power combination, and the above description can be referred to, that is, the content of the fourth processing and the fifth processing can be Please refer to the content description of the first processing, the second processing and the third processing above, which will not be repeated here.

It should be noted that the third signal, the fourth signal, the fifth signal, the sixth signal, the eighth signal, the ninth signal, and the tenth signal are all located on a first plane, and the first plane is perpendicular to the first direction The plane, the first direction is the direction in which the signal is transmitted between the first orthogonal unit and the second orthogonal unit, that is, the direction in which the signal is transmitted in the rotating unit.

It should be noted that, in a possible implementation, the above-mentioned first orthogonal unit and second orthogonal unit are OMTs. When adjusting the relative rotation angle of the two OMTs, it is also necessary to consider the main path end of the communication device, The influence of the docking angle between the auxiliary terminal, the isolation terminal and the common terminal #3 and other devices, for example, if the rotation angle is adjusted from θ ₁ to θ ₂ , considering the docking misalignment between the common terminal #3 and the antenna terminal, the maximum transmission rate can be guaranteed. The energy ratio is cos((θ ₂ -θ ₁ )/2), and the adjustment range of the rotation angle can be determined according to the specific acceptable energy attenuation in the current network.

As an example and not a limitation, the actual modeling and simulation calculation results are shown in Figure 8, where the abscissa represents the operating frequency of the communication device, and the ordinate represents the coupling amount of the communication device. It can be seen that the coupling amount proposed in this application can be In the working frequency range of the tuned communication device, the value of the coupling amount corresponding to each first included angle is relatively stable, the fluctuation of the coupling amount is small, and the coupling amount of the communication device has a high flatness in the passband.

In a possible implementation manner, the structure of the communication device 900 in this application is shown in FIG. 9 , the electrical performance part of the coupler is composed of two OMTs, the OMT1 adopts the front and rear outlets, and the front outlet is the main circuit end of the coupler , the rear outlet is the secondary end of the coupler, which is connected to the ODU. The two shunt ends of OMT2 are the right outlet and the front outlet. The right outlet is the common end of the coupler, which is separated and connected to the antenna through the flexible waveguide. The front outlet is the isolation end, which is connected to the matching load. The OMT2 can rotate at a certain angle. By rotating OMT2, the angle between the short side of common terminal #3 (that is, the side parallel to the electric field) and the short side of the main circuit end can be adjusted to 45deg. It is a balanced coupling device; in the same way, by rotating OMT2 to the short side of the common terminal #3, the angle between the short side of the main circuit end and the short side of the main circuit end is 30deg. At this time, the main circuit end has -1.3dB energy to the common port, and the secondary circuit end has - 6dB energy to the common port, it is an unbalanced coupling device.

In a possible implementation manner, the rotation of the OMT1 and/or OMT2 can be controlled by setting a rotary joint on the circular waveguide where the common terminal #1 and the common terminal #2 are butted, or a clip can be set on the communication device of the present application The angular rotation controller is used to control the rotation of OMT1 and/or OMT2, and the above-mentioned rotation angle can be continuously adjusted or node-type adjusted. The present application controls the relative rotation angle between OMT1 and OMT2 (that is, the first The specific implementation manner of the included angle) is not limited, as long as the solution that can adjust the relative rotation angle between the OMT1 and the OMT2 is within the protection scope of the present application.

Optionally, the communication device in this application can also be fixed by OMT2, OMT1 can be rotated by a certain angle, or both OMT1 and OMT2 can be rotated, as long as the relative angle between OMT1 and OMT2 can be adjusted. This is not limited.

Optionally, the common end of the OMT2 and the antenna may also adopt other installation and docking methods, such as integrated installation, etc., which is not limited in this application.

Optionally, OMT1 and OMT2 can also use other outlet forms, that is, the main circuit end and the auxiliary circuit end can also be installed on other surfaces of the OMT1 core, and the coupling end and the third common terminal can also be installed on the OMT2 core. In other respects, this application does not make any limitation here.

This application designs a communication device with an adjustable coupling amount. The coupling amount is only related to the relative angle (ie, the first angle) between the first orthogonal unit and the second orthogonal unit, and has nothing to do with the frequency, which can solve the problem of conventional Coupler problems are as follows:

1) The coupling amount of conventional windowed couplers (including broad-side couplers and narrow-side couplers) is related to frequency, and there is a certain fluctuation with frequency in the passband. The coupling amount of the communication device in this application has nothing to do with frequency, High flatness within the passband.

2) The bandwidth of the communication device proposed in the present application depends on the bandwidth of the OMT, because the OMT can realize wideband or even ultra-wideband. If the first orthogonal unit and the second orthogonal unit are OMTs, compared with the conventional coupler, the The communication device can greatly expand the operating frequency range of the directional coupler.

3) If the conventional window coupler needs to change the coupling amount, the corresponding coupling structure needs to be adjusted, such as the number, size, distance, etc. of the window opening. It is difficult to realize the normalization of directional couplers with different coupling amounts; the magic T cannot change the coupling amount ; The coupling amount of the communication device in this application is only related to the first included angle, and the required coupling amount can be achieved by rotating to a specific included angle. The adjustment method is simple and easy to implement, and couplers with different coupling amounts can be unified into one device.

Optionally, if the coupling amount adjustment method of the communication device in the present application is automatic adjustment, a possible adjustment method is as follows: first, the communication device determines an energy ratio according to a preset coupling amount, and the energy ratio includes the first quadrature The energy ratio of the input signal of the first port of the unit to the output signal of the fifth port of the second quadrature unit, or the input signal of the second port of the first quadrature body and the fifth port of the second quadrature body The energy ratio of the output signal of the port; then, the communication device determines, according to the energy ratio, a first included angle at which the first orthogonal unit and/or the second orthogonal unit rotates around a first direction, where the first direction is the signal the direction of transmission between the first orthogonal unit and the second orthogonal unit; finally, the communication device rotates the first orthogonal unit and/or the second orthogonal unit around the first direction, so that the first orthogonal unit The relative rotation angle between the unit and the second orthogonal unit is the first included angle, and the communication device reaches the preset coupling amount at this time.

In a possible implementation manner, the above-mentioned corresponding relationship between the preset coupling amount Y, the energy ratio X, and the first included angle θ satisfies the following conditions:

Y ₁ =20*log(cosθ)dB=20*log(X ₁ )dB

Y ₂ =20*log(sinθ)dB=20*log(X ₂ )dB

Wherein, Y ₁ is the coupling amount of the input signal of the first port of the first quadrature unit to the output signal of the fifth port of the second quadrature unit, and cosθ corresponds to the first quadrature unit of the first quadrature unit. The energy ratios X ₁ and Y ₂ of the input signal of one port and the output signal of the fifth port of the second quadrature unit are the ratio of the input signal of the second port of the first quadrature unit to the second quadrature unit. The coupling amount of the output signal of the fifth port, sinθ corresponds to the energy ratio X ₂ of the input signal of the second port of the first quadrature unit and the output signal of the fifth port of the second quadrature unit.
