Description

Five-in five-out coupling bridge

Technical Field

The invention relates to a five-in five-out coupling bridge, belongs to the field of mobile wireless communication, and effectively solves the problem that multiple paths of signals are combined and shunted to different antenna feeder antennas.

Background

Wireless communications can be divided into civilian mobile communications and national digital trunked communications (e.g., PMR, GSM-R, Tetra, etc.). Due to large government projects such as railways, communication coverage (sites, tunnels) and outdoor antenna feeder systems, indoor communication coverage (DAS) requires all signals to be combined to achieve extensive coverage to save costs. The existing coupling bridge or matrix has only the schemes of 2x2, 3x3 and 4x4, so the prior art uses the four-in four-out scheme at most. The prior art is not satisfactory if the number of input ports or output ports needs to be increased. Due to the lack of efficient multi-signal combining and splitting products, the related requirements can only be met by power-loss methods.

More difficult, if the input signals include 5 signals of GSM-R (railway communication), Tetra (terrestrial communication), mobile communication operator one 5, mobile communication operator two and mobile communication operator three, the 5 signals need to be combined and split into 5 mixed signals, and the existing coupling bridge or matrix cannot meet the requirements. And the requirements of the power output to the antenna according to different input signal types are different, for example, railway communication signals are required to be well covered in a tunnel, mobile communication cannot interfere with the railway signals, the power of the railway signals in the tunnel needs to be enhanced, and the requirements are difficult to meet by adopting the existing coupling bridge or matrix.

Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.

The 2x2 coupling bridge used in the present invention belongs to the prior art, and the bandwidth design requirement of 5 in and 5 out can be achieved by increasing the order of the 2x2 coupling bridge, so it is not described again. In the first to third embodiments, a 2 × 2 coupling bridge having a symmetrical structure as shown in fig. 1 is used. The 2x2 coupling bridge with a symmetrical structure comprises two input ports I and II and two output ports III and IV. In the invention, two input ports I and II are respectively defined as a symmetrical input port I and a symmetrical input port II, and two output ports III and IV are respectively defined as a symmetrical output port I and a symmetrical output port II, and the method comprises the following steps: the symmetrical output port I is a coupling port of the symmetrical input port I and is a connecting port of the symmetrical input port II; the symmetrical output port II is a connecting port of the symmetrical input port I and a coupling port of the symmetrical input port II.

Taking a 3dB coupler as an example, the power of the coupled output signal and the power of the direct-coupled output signal are each 1/2, that is, the input ports i and ii pass through the 3dB coupler to synthesize a signal one of 50% and a signal two of 50% to reach the output ports iii and iv respectively, and the signal one and the signal two have 20 to 30dB isolation. The two output ports III and IV of the 2x2 coupling bridge with the symmetrical structure have phases which are different by 90 degrees in the pass band.

In the fourth to eighth embodiments, 2 × 2 coupling bridges of an asymmetric structure as shown in fig. 2 are used. The 2x2 coupling bridge with an asymmetric structure comprises two input ports I and II and two output ports III and IV. In the invention, two input ports I and II are respectively defined as an asymmetric input port I and an asymmetric input port II; the two output ports iii and iv are respectively defined as an asymmetric output port one and an asymmetric output port two, and then: the asymmetrical output port I is a connection port of the asymmetrical input port I and is a connection port of the asymmetrical input port II; the asymmetric output port II is a connection port of the asymmetric input port I and a coupling port of the asymmetric input port II.

The principle of the asymmetric 2x2 coupling bridge is similar to that of the symmetric 2x2 coupling bridge, except that the phases of the signals at the two output ports are not 90 degrees within the pass band.

It should be noted that, in the same five-in five-out coupling bridge, the 2x2 coupling bridges with a symmetric structure (as described in the following embodiments one to three) may be used, and the 2x2 coupling bridges with an asymmetric structure (as described in the following embodiments four to eight) may be used. After reading this application, those skilled in the art can also use a mixture of a symmetric 2x2 coupling bridge and an asymmetric 2x2 coupling bridge.

The phase adjusting section 13 used in embodiments one to eight is a transmission line whose design length can be changed to function as a phase shifter. Those skilled in the art can design the length of the transmission line according to the specification of the five-in five-out coupling bridge, so that the power of the signals input to the input port one a and the input port two B in the five mixed signals reaches the expected power, and the corresponding narrow-band combining effect or width combining effect is realized.

Specifically, the phase adjustment unit 13 couples the first input signal and the second input signal to the symmetric 2x2 to form a composite signal after coupling the first input signal and the second input signal to the first bridge 1. Defining the phase of a path of the composite signal from the symmetrical output port one 103 of the symmetrical 2x2 coupling bridge one 1 to the symmetrical input port one 401 of the symmetrical 2x2 coupling bridge four 4 through the phase adjusting part 13 as a path phase one; defining the phase of the path from the second symmetric output port 104 of the first symmetric 2x2 coupled bridge 1 to the second symmetric input port 402 of the fourth symmetric 2x2 coupled bridge 4 as path phase two, there are: the first path phase is not matched with the second path phase by adjusting the phase adjusting part 13, so that the narrow-band synthesis effect is achieved; the first path phase is matched with the second path phase by adjusting the phase adjusting part 13, thereby achieving the broadband synthesis effect.
