Raio frequency back plate capable of realizing configuration switched

Abstract

The radio frequency back plate includes switching module in radio frequency and jumpers in radio frequency. The said switching module in radio frequency is in use for branching or joining signals in radio frequency. The said switching module in radio frequency also includes ports of jumpers in radio frequency. The said jumpers are in use for connecting ports to realize switching between different configurations. The disclosed radio frequency back plate solves issue that switching configurations are taken by modules. The invention reduces quantity of modules and quantity of signal wires so as to simplify maintenance. Advantages are: supporting blind inserting into and pulling out module in radio frequency; supporting operation at front face for switching configurations and saving space of equipment cabinet.

Description

technical field [0001] The invention relates to a backplane and radio frequency technology, in particular to realizing configuration switching of a radio frequency system on the backplane. Background technique [0002] In a multi-carrier Wideband Code Division Multiple Access ("WCDMA" for short) system, the implementation of the base station transmission path is as follows: figure 1 shown. Among them, f1~f4 are transmitters, which respectively use multiple carriers. The signals of each transmitter are modulated by different carriers and enter the synthesizer for synthesis, and then amplified by the power amplifier and then sent to the antenna through the duplexer. [0003] Since the Code Division Multiple Access ("CDMA") system is a self-disturbing system, the signal of each channel is the noise of other channels. Therefore, in the CDMA system, the total number of the system can be reduced by using directional antennas. noise. For example, in a WCDMA system, the 360° tran...

Problems solved by technology

[0015] In practical application, the above-mentioned scheme has the following problems: firstly, the existing scheme for realizing configuration switching needs to add a new module in the system, and secondly, the existing scheme for realizing configuration switching will result in adding many connecting cables

[0016] The main reason for this situation is that the existing scheme for realizing configuration switching is to realize the switching of system configuration by designing electronic switches or jumpers in the module, so a new module needs to be added. All modules need to be connected by signal wires, so many connecting cables are added in the system
