Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] In the 1-100GHz application frequency range, based on the performance of the above structure, we proposed a novel petal-shaped 1-4 waveguide power divider that can effectively reduce the volume on the basis of referring to the commonly used waveguide power divider and matching structure. structure, and has good insertion loss and reflection indicators in a 20% wide frequency band. The petal-shaped power splitter adopts a petal-shaped special-shaped cavity structure instead of the traditional 2-level 1-point 2-waveguide T-shaped power splitter structure, which makes 1 point 4 power points only need one level of power points to be realized. In large arrays such as 1024 In the unit, the number of power dividers in the last stage is saved, that is, 512 1-to-2 power dividers, which greatly reduces the difficulty of processing and wiring lar...

Abstract

The invention discloses a petal-shaped one-to-four waveguide power divider. The power divider comprises a power divider cavity; a first port, a second port, a third port, a fourth port and a fifth port are integrally formed in the power divider cavity; the first port is located at the central position of the power divider cavity and is used as a main port; the first port partially protrudes out ofone surface plane of the power divider cavity; the second port, the third port, the fourth port and the fifth port all protrude out of the other surface plane of the power divider cavity; the first port is connected with input signals; the second port, the third port, the fourth port and the fifth port are all connected with a post-stage circuit; and electromagnetic waves enter the power dividercavity from the first port and are uniformly transmitted or radiated out the from four symmetrical branch ports on the other end plane of the cavity through the transmission and resonance of the powerdivider cavity. According to the petal-shaped one-to-four waveguide power divider of the invention, the problems of too many stages, complex processing and insufficient wiring space of a power divider in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical fields of mobile communication and microwave transmission, and in particular relates to a petal-shaped 1-to-4 waveguide power divider. Background technique [0002] A power divider is a commonly used device in a microwave passive system that can distribute the energy of one input signal into multiple signal energies according to engineering requirements. It is used in phase shifters, power adjusters, T-joints of duplexers and porous slit couplers, and can also be used to distribute intermediate frequency signals of satellite receivers connected to antennas; in wireless communications, the output of a single solid-state device Power is limited as frequency increases, and another use of a power combiner is a good remedy for this limitation. The reverse use of the power divider can combine several dispersed energies at the same time to achieve the purpose of high power output. [0003] There are many types of power...
