Abstract
The utility model provides a broadband three-way power divider, which relates to the technical field of electronics and aims at solving the technical problem that a traditional product is narrow in operation bandwidth, large in insertion loss, poor in batch processing consistency, not high in stability and integrated level and the like. The broadband three-way power divider is formed by a three-way power dividing input port, a three-way power dividing isolation resistor, three three-way power dividing transmission and conversion sections and three output ports. The input port, the transmission and conversion sections and the three output port are microstrip printing lines, and one transmission and conversion section is respectively arranged between the input port and the three output ports. The upper three-way power dividing transmission and conversion section and the lower three-way power dividing transmission and conversion section are in a sine rectangular wave shape, and the wave shapes are the same. The middle transmission and conversion section is in a shape of S-shaped waves which are connected in head-to-tail mode, the chamfer wave crest and the chamfer wave trough of the three transmission and conversion sections are impedance conversion sections, and impedance conversion nodes are arranged in the middle of three close sections between the upper transmission and conversion section and the lower transmission and conversion section and connected with each other through three isolation resistors.
Description
Technical field
The utility model relates to electronic technology field, particularly a kind of three synthetic power splitters of wideband array antenna beam that are applied to.
Background technology
Broadband three power splitters are critical elements of wideband array antenna, are mainly used in the formation wave-packet portion of wideband array antenna, and existing broadband three power splitters mainly are made up of the universal electric element, the following weak point of ubiquity:
1) work zone width;
2) the insertion loss is big;
3)The batch machining consistency is poor, and stability is not high;
4)Integrated level is not high.
Summary of the invention
The utility model is intended to solve traditional product work zone width, insert that loss is big, the batch machining consistency is poor, stability is not high, integrated level high-technology problem not, has to provide that the plane is integrated, in light weight, high conformity, stability are high, insert broadband three power splitters of advantages such as loss is little.
The purpose of the utility model realizes through following technical scheme.
Broadband three power splitters of the utility model; Divide input port, three merits to divide isolation resistance, three three merits to divide propagation and transformation section, output armatine, output port second and output port third to constitute by three merits; Wherein three merits divide input port, three merits to divide propagation and transformation section, output armatine, output port second and output port third to be the microband printing line; Three merits are divided between input port and three output ports respectively has one three merit to divide the propagation and transformation section; Wherein up and down two three merits to divide the propagation and transformation section to be sinusoidal rectangle wavy, and waveform is relative; It is wavy that middle one three merit divides the propagation and transformation section to be end to end S shape; Article three, to divide the corner cut crest of propagation and transformation section and corner cut trough be transformer section to three merits; Two three merits are divided three intersegmental close section middle parts of propagation and transformation to be provided with three merits and are divided the impedance conversion node up and down, and divide isolation resistance to connect through three three merits respectively.
The beneficial effect of the utility model broadband three power splitters:
1. employing microstrip line construction, the dielectric constant of micro-strip line substrate medium is 2.2, thereby product to insert loss little, the batch machining consistency is high, the debugging amount is few;
2. cavity uses the aluminium manufacturing, and product weight is light;
3. the plane is integrated, stability is high.

Embodiment
The utility model detailed structure, application principle, effect and effect with reference to accompanying drawing 1-2, are explained through following execution mode.
The utility model divides input port, three merits to divide isolation resistance, three three merits to divide propagation and transformation section, output armatine, output port second and output port third to constitute by three merits; Wherein three merits divide input port, three merits to divide propagation and transformation section, output armatine, output port second and output port third to be the microband printing line; Three merits are divided between input port and three output ports respectively has one three merit to divide the propagation and transformation section; Wherein up and down two three merits to divide the propagation and transformation section to be sinusoidal rectangle wavy, and waveform is relative; It is wavy that middle one three merit divides the propagation and transformation section to be end to end S shape; Article three, to divide the corner cut crest of propagation and transformation section and corner cut trough be transformer section to three merits; Two three merits are divided three intersegmental close section middle parts of propagation and transformation to be provided with three merits and are divided the impedance conversion node up and down, and divide isolation resistance to connect through three three merits respectively.
These broadband three power splitters use the microstrip line printed conductor structure, are made up of little band track and isolation resistance.Microstrip line directly is divided into three the tunnel through impedance conversion, and isolation resistance is connected across impedance conversion point place between the two paths of signals line, adopts the high performance resistance of high accuracy, and operating frequency covers L, S, C, Ku, K wave band, and highest frequency can reach the Ka wave band.Be equally divided into three the tunnel from the signal energy of public port input, homophase outputs to three ports.Between two-port because a little less than having energy that isolation resistance receives signal each other very, form isolation.
Referring to accompanying drawing 2, the utility model is when concrete the application, and input port connects outside source, and output port links to each other with antenna 1, antenna 2 and antenna 3 respectively.
