Description

High-isolation homologous ray mixer
Technical field
The present invention relates to a kind of mixer, especially relate to a kind of high-isolation homologous ray mixer.
Background technology
The homologous ray mixer is a kind of the two paths of signals energy to be mixed, and is divided into that two-way output equates or the device of unequal energy, generally is used for
The important technological parameters of homologous ray mixer has voltage standing wave ratio, the isolation between the power input port, power capacity and the working band width etc. of power loss (comprise insert loss, distribute loss and reflection loss), each port, and wherein the isolation between the power input port is unusual important index.
It is the patent documentation of CN1988248A that State Intellectual Property Office of the People's Republic of China discloses publication number on 06 27th, 2007, title is a kind of mixer, it comprises cavity body filter, microwave circulator, the belt direction setting of electromagnetic wave energy in the described microwave circulator is that port one is to port 2, port 2 is to port 3, described cavity body filter is connected to 1 port of microwave circulator, cavity body filter and microwave circulator port one constitute mixer input port 1 jointly, 2 ports of microwave circulator are mixer public output mouth, and microwave circulator 3 ports constitute the input port 2 of mixer.This scheme realizes the isolation of two ports jointly by circulator and filter, and complex structure is processed loaded down with trivial detailsly, and cost is higher.
Summary of the invention
The technical problem that the present invention mainly is a solution existing in prior technology complex structure, processing is loaded down with trivial details, cost is high provides a kind of processing simple in structure, easy, lower-cost high-isolation homologous ray mixer.
The present invention is directed to above-mentioned technical problem is mainly solved by following technical proposals: a kind of high-isolation homologous ray mixer, comprise at least three blocks of dielectric-slabs and two coupling lines, coupling line is clipped between two blocks of dielectric-slabs with differing dielectric constant, article two, accompany one deck dielectric-slab in the middle of the coupling line, coupling line is provided with little band fine rule, little band fine rule one end is connected with coupling line, and the other end of little band fine rule is unsettled.Tradition homologous ray mixer adopts the sheet material with a kind of dielectric constant, because the dispersion characteristics of little band, the transmission phase velocity of Qi Mo and even mould is different, causes interport isolation to be difficult to improve.Adopt and mix the transmission phase velocity that the different medium material can be regulated strange mould and even mould, improve the interport isolation of homologous ray mixer.On coupling line, increase little band fine rule, the transmission phase velocity that can regulate strange mould and even mould, the interport isolation of raising homologous ray mixer.
Dielectric-slab is 5, each dielectric-slab is stacked, be respectively first dielectric-slab, second dielectric-slab, the 3rd dielectric-slab, the 4th dielectric-slab and the 5th dielectric-slab from top to bottom, first dielectric-slab adopts identical dielectric constant material with the 5th dielectric-slab, second dielectric-slab adopts identical dielectric constant material with the 4th dielectric-slab, the dielectric constant of the 3rd dielectric-slab is less than the dielectric constant of second dielectric-slab, and the dielectric constant of second dielectric-slab is less than the dielectric constant of first dielectric-slab.Adopt multilayer dielectricity the plate better strange mould and the even mould phase velocity of balance electromagnetic signal.
Coupling line comprises first coupling line and second coupling line, and first coupling line is clipped between second dielectric-slab and the 3rd dielectric-slab, and second coupling line is clipped between the 3rd dielectric-slab and the 4th dielectric-slab.Whole system is two inputs, and two outputs after two input signals can being mixed, are divided equally and outputed to two outputs.
First coupling line and second coupling line include interface end and linear coupled section of two arcs, and little band fine rule is connected to the two and the centre of coupled section, and little band fine rule width is that 0.5mm is to 1.5mm.。
The coupled section of first coupling line is parallel with the coupled section of second coupling line, two relative the 3rd dielectric-slab symmetries of coupled section.
The substantial effect that the present invention brings is, has simple structure, processing easily, and cost is low, has higher isolation, can reach more than the 35dB.
