Embodiment Construction

[0031] In order to facilitate a further understanding of the present invention, the present invention will now be described in detail in conjunction with the accompanying drawings.

[0032] see figure 2 , this figure shows the schematic diagram of the internal structure of the POI multi-system cable combining equipment of the present invention, including 2 power dividers, 3 3DB bridges, and 2 six-frequency combiners, wherein all the 2 power dividers and 3DB power dividers The bridge is connected to the six-frequency combiner one and the six-frequency combiner two respectively, and the six-frequency combiner one and the six-frequency combiner two are respectively connected to the port one (ANT1) and the port two (ANT2). The six-frequency combiner 1 and the six-frequency combiner 2 are respectively connected to a port for direct access to the PHS system. The structure of the device is as image 3 As shown, the performance indicators are shown in Table 1:

Abstract

The present invention discloses a multi-system multiplexing platform cable combining apparatus which comprises power dividers and 3DB electric bridges, a six-frequency combiner 1 and a six-frequency combiner 2. The power dividers and 3DB electric bridges are respectively connected with the six-frequency combiner 1 and six-frequency combiner 2. When the apparatus according to the invention is adopted, the main performance indexes of insertion loss, in-band fluctuation, echo loss, out-of-band rejection, third order inter-modulation, bearing power and the like of the POI are equally improved with a large scale. At the same time the structural volume is reduced with a large scale and the application in the project is facilitated.

Description

technical field [0001] The invention relates to a POI (multi-system integration platform) multi-system cable combination equipment. Background technique [0002] With the rapid increase of mobile users and more and more high-rise buildings in cities, the traffic density and coverage requirements are also rising. These buildings are large in scale and of good quality, and have a strong shielding effect on mobile phone signals. In the environment of low floors of large buildings, underground shopping malls, underground parking lots, etc., the mobile communication signal is weak, and the mobile phone cannot be used normally, forming a blind area and shadow area of ​​mobile communication; on the middle floor, due to the overlapping of signals from different surrounding base stations, The ping-pong effect is generated, the mobile phone is switched frequently, and even the call is dropped, which seriously affects the normal use of the mobile phone; in the high-rise buildings, due...
