The embodiment of the present invention relates to the field of communications, and particularly relates to a power combining and allocating device, aiming at improving power capacity of a power combining and allocating device. The power combining and allocating device of the embodiment comprises: a cavity formed by sealing a first cavity shell and a second cavity shell; and located in the cavity, a center conductor and a number N of branch conductors. N is a positive integer greater than 1. A first port and N second ports are formed in the first cavity shell; the first port is used for outputting synthesized signals or inputting signals to be decomposed; and each of the N second ports is used for inputting signals to be synthesized or outputting decomposed signals. The center 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 heads of the branch conductors are located in the second port, and the bottoms of the branch conductors are fixed on a 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...
