Description

Technical Field

[0001] The utility model belongs to the field of power dividers, in particular to a two-way multi-power divider. Background Art

[0002] A power splitter is a device that divides one input signal energy into two or more outputs with equal or unequal energy. It can also combine multiple signal energies into one output, which is also called a combiner. Traditional power splitters are all one-to-many power splitters. When there are more than two signal energy inputs, the solution is often to simply increase the number of power splitters. This simple increase in number often brings the disadvantages of increased layout size and overall size. The split layout of the power splitter also causes trouble in occasions where the length of the RF cable is required. Utility Model Content

[0003] In view of this, the utility model aims to propose a two-way multi-power splitter to solve the disadvantages of increased layout size and overall size caused by the increase in the number of power splitters when there are more than two signal energy inputs, and the split layout of the power splitter also causes troubles in occasions where there are requirements for the length of RF cables.

[0010] Furthermore, it also includes a plurality of outlet SMA pan head screws, and a plurality of outlet SMA seats are respectively installed to the other side of the upper shell and the lower shell through the outlet SMA pan head screws.

[0011] Furthermore, the number of outlet SMA seats installed on one side of the upper shell is equal to the number of outlet SMA seats installed on one side of the lower shell.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figures 1 to 4 As shown, a two-way multi-power divider includes a cover plate countersunk screw 1, a cover plate 2, a PCB pan head screw 3, a one-to-six power divider PCB 4, a shell countersunk screw 5, an upper shell 6, an inlet SMA pan head screw 7, an inlet SMA seat 8, a lower shell 9, an outlet SMA seat 10, and an outlet SMA pan head screw 11.

[0027] Structurally, this two-way multi-power splitter designs two one-way multi-power splitters into one power splitter. The two-dimensional installation space will be consistent with the size of a traditional power splitter. The weight is also reasonably optimized by optimizing the internal cavity size and connection form, solving the problem of increased layout size and overall size due to the increase in the number of power splitters when traditional multi-channel signal input is used.

[0028] like Figure 1 This is the overall structure diagram of the two-to-twelve power divider in this implementation scheme, which is actually divided into two one-to-six power divider networks.

[0029] like Figure 2 The figure shows an exploded view of a two-to-twelve power divider, the shell includes an upper shell 6 and a lower shell 9, the upper shell 6 and the lower shell 9 are connected by shell countersunk screws 5, the upper and lower one-to-six power divider PCBs 4 are respectively fixed to the upper shell 6 and the lower shell 9 by PCB pan head screws 3, the lower surface of the one-to-six power divider PCB 4 is in close contact with the shell, the upper and lower cover plates 2 are fixed to the shell by cover plate countersunk screws 1, the two inlet SMA seats 8 are respectively fixed to the upper and lower shells by inlet SMA pan head screws 7, and the 12 outlet SMA seats 10 are respectively fixed to the upper and lower shells by outlet SMA pan head screws 11.

[0030] The two-to-twelve power divider is equivalent to two one-to-six power dividers, specifically, two identical one-to-six circuit boards are respectively installed on the upper and lower shells, and the upper shell 6 and the lower shell 9 are connected by the shell countersunk screws 5 to ensure that the upper shell 6 and the lower surface of the one-to-six power divider PCB 4 can still have good contact without affecting the electrical performance. The separate design of the upper and lower shells is conducive to making the shell into a cavity, such as Figure 3 , minimizing the shell weight.

[0031] The two-to-twelve power splitter has six SMA RF sockets 10 at the top and bottom, and the two outputs are arranged vertically, which minimizes the horizontal size and is conducive to the layout design of cables of equal length for different signals.

[0032] The upper shell 6, the lower shell 9 and the cover plate 2 of the two-to-twelve power divider adopt a step design to ensure good shielding of the radio frequency signal and avoid electromagnetic leakage caused by installation flatness error.

[0033] Advantages of this utility model:

[0034] The small size and high integration design greatly reduces the volume and weight of the power divider when multiple signals are input.

[0035] The feeding network of the two-way power divider can still use the hardware design of the traditional power divider to ensure the consistency of the feeding network and facilitate mass production.

[0036] The output ports of the two-way power divider are arranged vertically with no deviation in horizontal position, which brings great convenience to the occasions where the layout of cables with equal length is required for multiple output signals.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
