Novel equal-phase multi-channel power divider

Abstract

The invention discloses a novel equal-phase multichannel power divider, which comprises a shell and power dividing plates arranged in the shell, and is characterized in that the power dividing platescomprise a first power dividing plate and at least two second power dividing plates, the plurality of second power dividing plates are arranged in parallel, and the first power dividing plate is vertically arranged at one side of each second power dividing plate; the first power dividing plate is provided with a first microstrip line with input ends and output ends, the number of the output ends of the first microstrip line equals that of the second power dividing plates, the second power dividing plates are provided with second microstrip lines with the input ends and the output ends, and theinput ends of the second microstrip lines are connected with the output ends of the first microstrip line. According to the invention, multiple power dividing polates are included and combined combined into a three-dimensional space; the transverse size of the power divider is reduced, the longitudinal size of the power divider is increased, the area of the power dividing plate can be increased,the distance between the microstrip lines is increased, the consistency of the power divider is not affected, the size of the power divider is reduced, and the requirement of a traditional power divider for installation space is met.

Description

technical field [0001] The invention relates to the field of power dividers, in particular to a novel equal-phase multi-channel power divider. Background technique [0002] With the rapid development of wireless communication, the requirements for radio frequency communication are getting higher and higher. The output power of a single microwave device has been difficult to meet the needs of high-power systems. Therefore, it is necessary to use multiple devices to realize the power distribution of the system through power distribution. Require. The power divider is referred to as the power divider for short. It is a common microwave passive device in the RF front end. It is mainly used for the distribution and synthesis of signal power. It is usually used in mixers, power amplifier circuits, jammers, modems, phase control In various microwave radio frequency systems such as array radar antennas. With the popularization of mobile devices, the structure of microwave radio fr...

Problems solved by technology

With the popularization of mobile devices, the structure of microwave radio frequency needs to be miniaturized, so the reserved space for the installation of the power splitter is reduced. Most of the existing power splitters are realized by a power splitter board with a microstrip line. There is one input interface and several output interfaces connected on the board, and the output interfaces are arranged in a row, such as figure 1 As shown, in order to reduce the volume and size, it is often used to reduce the distance between the microstrip lines, and then reduce the volume of the power splitter. This will lead to a large phase dispersion of the power splitter and affect the phase consistency.
