A two-power division input port of a broadband two-power divider of the broadband four-power divider of the utility model is connected with an external input source; two output ports of the broadband two-power divider of the broadband four-power divider are connected with the two-power division input port of a secondary broadband two-power divider, respectively.

Description

Broadband four power splitters

Technical field

The utility model relates to electronic technology field, particularly a kind of four synthetic power splitters of wideband array antenna beam that are applied to.

Background technology

Broadband four 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 four 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 four power splitters of advantages such as loss is little.

The purpose of the utility model realizes through following technical scheme.

Broadband four power splitters of the utility model, two merits of broadband two power splitters divide input port to connect outside input source, and its two output ports respectively connect two merits of secondary broadband two power splitters and divide input port.

Broadband four power splitters of the utility model; Wherein said broadband two power splitters divide input port, two merits to divide isolation resistance, two two merits to divide propagation and transformation section, output port one and output port two to constitute by two merits; Wherein to divide input port, two merits to divide propagation and transformation section, output port one and output port be the microband printing line to two merits; Two merits divide input port and output port one, two of output ports respectively to have one to be two wavy merits of sinusoidal rectangle and to divide the propagation and transformation section; Article two, two merits divide the waveform of propagation and transformation section relative; Its corner cut crest and corner cut trough are that two merits are divided transformer section, and three close section middle parts between the two are provided with two merits and divide the impedance conversion node, and divide isolation resistance to connect through three two merits respectively.

The beneficial effect of the utility model broadband four 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 1-3, are explained through following execution mode.

The utility model divides input port to connect outside input source by two merits of broadband two power splitters, and its two output ports respectively connect two merits of secondary broadband two power splitters and divide input port.

Aforesaid broadband two power splitters divide input port, two merits to divide isolation resistance, two two merits to divide propagation and transformation section, output port one and output port two to constitute by two merits; Wherein to divide input port, two merits to divide propagation and transformation section, output port one and output port be the microband printing line to two merits; Two merits divide input port and output port one, two of output ports respectively to have one to be two wavy merits of sinusoidal rectangle and to divide the propagation and transformation section; Article two, two merits divide the waveform of propagation and transformation section relative; Its corner cut crest and corner cut trough are that two merits are divided transformer section; Three close section middle parts between the two are provided with two merits and divide the impedance conversion node, and divide isolation resistance to connect through three two merits respectively.

These broadband four power splitters use the microstrip line printed conductor structure, are made up of little band track and isolation resistance.Microstrip line is divided into four 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 four the tunnel from the signal energy of public port input, homophase outputs to four ports.Between port because a little less than having energy that isolation resistance receives signal each other very, form isolation.

Referring to accompanying drawing 3, the utility model is when concrete the application, and input port connects outside source, and output port links to each other with antenna 1-4 respectively.
