Power synthesis distribution device

Abstract

The embodiment of the invention relates to the field of communication, in particular to a power synthesis distribution device, which is used for improving power capacity of the power synthesis distribution device. The power synthesis distribution device comprises a cavity formed by sealing a first cavity shell and a second cavity shell, a central conductor, N branch conductors, wherein the centralconductor and the N branch conductors are located in the cavity, and N is a positive integer larger than 1; the first cavity shell is provided with a first port and N second ports; the first port isused for outputting a composite signal or inputting a to-be-decomposed signal; each second port of the N second ports is used for inputting a to-be-synthesized signal or outputting a decomposed signal; the central conductor comprises a first connector and a first base; the first connector is located in the first port; the first base is fixed on the inner wall of the second cavity shell; the head of each of the branch conductors is located in the second ports, wherein the bottom of each of the branch conductors is fixedly arranged on the side wall of the first base.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a power combining and distributing device. Background technique [0002] In radar and communication systems, power amplifiers are used more and more widely. However, due to limitations of technology and technology, the single-tube output power of power amplifiers is limited, especially in high-frequency power applications. The disadvantages are more obvious. In order to meet the output requirements of high-frequency and high-power signals, a power combining and distributing device must be used. [0003] Traditional binary power combining splitters, such as Wilkinson power splitters and branch line couplers, are only used in small power combining, and they are combined step by step, and the combining efficiency is low. capacity needs. The waveguide T-junction power combiner that meets high-power applications also needs to be combined step by step, the c...
