Description

Combiner Sub Rack compatible for different LPA}

The present invention relates to an LPA mixed combiner sub-rack which can use LPAs of different standards among the LPAs used in the mobile communication base station.

Currently, more than half of Korea's population uses mobile communications, and its users are expected to increase. The mobile communication is performed by the base station communicating with the subscriber terminal and transmitting and receiving the voice signals.

In the mobile communication base station, a linear power amplifier (LPA) and a high power amplifier (HPA) are disposed in a sub rack, and the LPA and HPA transmit RF signals to the subscribers in the far distance. An amplifier that amplifies the power of an RF signal so that it can be transmitted.

In the above, LPA is used in a cellular mobile communication system, and HPA is used in a mobile communication system.

The LPA used in the cellular mobile communication system has three types of standards of 25W, 50W, and 60W.

Hereinafter, with reference to the accompanying drawings with respect to the configuration and operation of the embodiment of the present invention will be described.

Figure 2a is a side coupling of the mixed combiner sub-rack for the LPA of the present invention.

FIG. 2B is a front view of FIG. 2A.

Referring to FIGS. 2A and 2B, the present invention includes an LPA 5 for amplifying the power of an RF signal and a sub rack 10 to which the LPA 5 is coupled.

In addition, the detailed configuration of the sub rack 10 is a top guide 15 to which the upper guide rail 5a of the 60W LPA 5 is coupled, a bottom guide 20 to which the lower is coupled, and 25W and 50W The top slide bracket 30 coupled to the bottom of the top guide 15, the bottom slide bracket 35 coupled to the top of the bottom guide 20, and the plurality of LPAs so that the LPA 5 may be coupled thereto. A combiner 25 for synthesizing the power of 5) and an adapter 40 for power matching the LPA 5 for the 25W and 50W with the combiner 25.

The top slide bracket and the bottom slide bracket will be described in detail with reference to FIGS. 3 and 4 as follows.

3 is a detailed view of the top slide bracket of the present invention.

4 is a detailed view of the bottom slide bracket of the present invention.

First, the top slide bracket will be described with reference to FIG. 3. The top slide bracket 30 is coupled to the top guide rail 5a of the LPA 5 for the 25W and 50W, and the LPA 5 and the sub rack. Top guide (30a) of the concave-convex structure is installed on the bottom of the existing 60W top guide (15) installed to guide the coupling of the 10, and the top slide bracket (30) is the top guide (15) of the sub rack (10) It consists of a screw (30b) to be fixed to be installed at the bottom.

In addition, the bottom slide bracket will be described with reference to FIG. 4. The bottom slide bracket 35 is coupled to the lower guide rail 5a of the LPA 5 for the 25W and 50W, and the LPA 5 and the sub rack. The bottom guide 35a of the groove structure installed on the top of the bottom guide 20 for 60W and the bottom slide bracket 35 are installed to guide the coupling of the bottom 10. It consists of a screw (35b) for fixing so that it can be installed on the top.

Referring to the accompanying drawings with respect to the operation of the present invention made of the above configuration are as follows.

5 is a perspective view of the combination of the combination combiner sub rack for LPA of the present invention.

Referring to FIG. 5, the sub rack 10 illustrated in FIG. 5 may be combined with a total of four LPAs 5, and the left three may be combined with LPAs 5 for 25W and 50W. The top slide bracket 30 and the bottom slide bracket 35 are coupled, and the right one is provided with a top guide 15 and a bottom guide 20 so that the LPA 5 for 60W can be coupled.

First, if the user wants to combine the 60W LPA (5) to the sub rack 10, the top guide 15 and the bottom guide 20 at the right end of the upper and lower guide rails of the 60W LPA (5) What is necessary is just to combine (5a).

In addition, in order for the user to combine the 25W, 50W LPA 5 to the sub rack 10, the top slide bracket 30 and the top guide 15 and the bottom guide 20 installed in the existing sub rack 10 The bottom slide bracket 35 is installed using screws 30b and 35b.

When the top slide bracket 30 and the bottom slide bracket 35 are installed on the three top guides 15 and the bottom guide 20 on the left side of the sub rack 10, the user may use the LPA for 25 W and 50 W ( The upper and lower guide rails 5a of 5) are coupled to the top guide 30a of the top slide bracket 30 and the bottom guide 35a of the bottom slide bracket 35 to form the LPA 5 for 25W and 50W. To be coupled to the sub rack 10.

When using the 60W LPA (5) instead of the 25W, 50W LPA (5), the screw (30b, 35b) of the top slide bracket 30 and the bottom slide bracket 35 installed in the sub rack 10 By disassembling, the guide rail 5a of the 60W LPA 5 may be coupled to the top guide 15 and the bottom guide 20 previously installed.

Through all the above processes, the LPA mixed combiner subrack is implemented as intended by the present invention.

As can be seen from the above description, the present invention provides a top guide installed in an existing subrack to simultaneously use 25W, 50W LPA and 60W LPA in a subrack in which a power amplification LPA used in a base station is combined. Combine the top slide bracket consisting of the top guide and screw on the bottom and the bottom slide bracket consisting of the bottom guide and screw on the top of the bottom guide to combine the LPA for 25 and 50W, which is smaller than the 60 W LPA. The effect of combining 25W and 50W LPAs in a subrack where only LPAs can be used, and since the two types of LPAs can be freely arranged according to a user's intention and do not have to have subracks for each type, It has elastic operation and economic effect.
