Description
Technical field
The present invention relates to a kind of orthogonal mode adapters.Specifically, being related to a kind of handling ease, machining accuracy is easily guaranteed that
Orthogonal mode adapter.
Background technology
Orthogonal mode adapter（Orthogonal Mode Transducer, OMT）It is the key element in satellite communication.
In linear polarization operating mode, the linear polarization mode that square crossing is respectively adopted in the signals of uplink and downlink is propagated.Orthogonal mode turns
Device is connect as three port devices.According to polarization direction difference, orthogonal mode adapter is by uplink and downlink Signal separator, from different port
It outputs and inputs.Traditional orthogonal mode adapter is three-dimension device, general using die sinking forging type production.When product batch
When little, this method cost is very high.It is improved in signal frequency, in particular to millimeter wave and during Terahertz frequency range, traditional die sinking
Casting method may be because that precision is too poor and is difficult to meet the requirements.
Invention content
The purpose of the present invention is to provide a kind of precision to be easily guaranteed that, the low orthogonal mode adapter of processing cost.
To achieve these goals, the technical solution adopted by the present invention is as follows：
Orthogonal mode adapter, including a coupler and lateral output terminal.The coupler include at least 2 section coupled sections from
It is left-to-right to be interconnected.The coupler is connected in rear direction with lateral output terminal.In all coupled sections from left to right, first
Cuboid of the coupled section for an axis along from left to right direction is saved, the width of left side and the difference of height are less than 20%.Make
For preferable realization method, first segment coupled section is an axis along the cuboid in from left to right direction, the width of left side
Degree is equal to its height.
For the ease of being processed using milling, the shape of each coupled section is column of the axis in Z-direction.As preferred
Scheme, the shape of each coupled section is respectively cuboid of a line in Z-direction.
For the ease of processing and reducing installation bit errors, the upper surface of all coupled sections of the orthogonal mode adapter is neat
It is flat.This design allows that the orthogonal mode adapter is divided into pedestal and cover board two parts pass through milling using general-purpose machining center and add
Work is completed.Its bit errors of cover board lower surface between plane, with pedestal will not cause being remarkably decreased for device performance.
Design for lateral output terminal and longitudinal output end, there are two types of schemes：
The first scheme, the cross section of the transverse direction output terminal are more than its height for rectangle and its width.
At this moment, the right end of the coupler is connect with longitudinal output end；The cross section at the longitudinal output end is rectangle；Institute
The width for stating rectangle longitudinal output end is less than its height；Normal at the center at the rectangle longitudinal output end with it is described from left to right
First segment coupled section cross section center at normal direction overlap.
Second scheme, the cross section of the transverse direction output terminal are more than its width for rectangle and its height.
At this moment, the right end of the coupler is connect with longitudinal output end；The cross section at the longitudinal output end is rectangle；Institute
The height for stating rectangle longitudinal output end is less than its width；Normal at the center at the rectangle longitudinal output end with it is described from left to right
First segment coupled section cross section center at normal direction overlap.
It is emphasized that in order to ensure the orthogonal mode adapter because with signal realize polarization it is matched need around its first
When saving the axis rotation of coupled section, convenient for the device remains stationary being longitudinally attached thereto using rotary joint guarantee, which indulges
Normal direction to the center of the normal at the center of output terminal and the cross section of the first segment coupled section from left to right
It must overlap.For this purpose, in the present invention, the longitudinal output end is the connectivity port except the orthogonal mode adapter.This arrangement,
The orthogonal mode adapter is allow to be divided into cover board and pedestal.Pedestal therein may be used machining center and disposably machine,
The bottom surface of its cover board is plane simultaneously.When the cover board is with floor installation, the bit errors between them are to the orthogonal mode adapter
Performance have not significant impact.
Meanwhile during actual processing, the junction between the coupled section needs to carry out chamfered, in order to adopt
It completes to process by milling mode with numerical control machining center.
