Description
Technical field
The invention belongs to electronic communication technology field, particularly relate to a kind of waveguide coaxial connecter exported from narrow limit dress
Put.
Background technology
Waveguide coaxial connecter device is radar system devices, navigation system devices, microwave telecommunication devices and microwave test system
An extremely important passive device in system.For electromagnetic wave signal in waveguide being converted to coaxially or in microstrip transmission line,
It is easy to system and carries out follow-up signal processing.
The design of waveguide coaxial connecter device requires: Insertion Loss is little, and standing wave is low, it is roomy to carry, volume is little.Current modal square
Shape waveguide coaxial connecter device has two kinds, and one is modal orthogonal modes waveguide coaxial connecter device, the ripple of this kind of form
Lead coaxial conversion equipment coaxial output line mouth and be positioned at the broadside of waveguide；The second is the waveguide coaxial connecter device of termination form,
This kind of form coaxial port is exported by the terminal area of rectangular waveguide.
In microwave electron system, due to system structure layout and system compact requirement, generally require straight
Connect the narrow limit from waveguide and be coupled out electromagnetic wave signal, in order to system carries out signal processing.In this case, above two waveguide
Coaxially change due to the inherent shortcoming of its structure, all can not be directly realized by from the narrow limit of waveguide export, it is necessary to coordinate waveguide or
The a series of turning structure of cable could realize.Consequently, it is possible to inherently bring volume and weight to increase, it is unfavorable for total system
The small form factor requirements of system, cost increases, and increases complete machine complexity simultaneously, deteriorates systematic function.
Summary of the invention
Present invention aim at the defect for existing waveguide coaxial connecter device, it is provided that a kind of can be directly from waveguide
The waveguide coaxial connecter device of narrow limit output.
The present invention for achieving the above object, adopts the following technical scheme that
A kind of waveguide coaxial connecter device exported from narrow limit, including rectangular waveguide and coaxial port, it is characterised in that: described same
Axle head mouth is positioned at the narrow limit of described rectangular waveguide；Another narrow limit of the rectangular waveguide relative with narrow limit, described coaxial port place
One jiao is provided with a step；Being provided with the boss with multiple step in described rectangular waveguide cavity, the plurality of step depends on
Secondary increasing, lowest-order step is right against the direction of waveguide mouth, and remaining step is turned round and turn 90 degrees just square wave to coaxial port output
The narrow edge direction led, described coaxial port is positioned at high-order step.
Preferred: described boss has three steps.
A gap is opened at the described top of high-order step, and the welding for coaxial connector inner core positions.
Its number of steps being further characterized by described boss requires to synchronize to increase with according to bandwidth of operation.
The coaxial port of waveguide coaxial connecter device of the present invention is arranged on the narrow limit of rectangular waveguide, close at rectangular waveguide
The boss structure that a band is turned is designed in end, the inner core of coaxial connector is directly welded at boss top, it is achieved waveguide
To coaxial translation function.The waveguide coaxial connecter device of this form has the widest relative bandwidth equally, relatively low standing wave and
The least Insertion Loss.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is the simulation curve figure of waveguide coaxial connecter device.
Detailed description of the invention
Fig. 1 is the interior three-dimensional figure of the coaxial conversion equipment of novel waveguide, including the port of rectangular waveguide 1；2 is 50 ohm
This port of coaxial port 2(can also be microstrip line port as required)；Rectangular waveguide 1 away from coaxial port 2 while cutting
Opening a step 3, the size controlling the long and wide both direction of described step 3 can improve returning of whole waveguide coaxial connecter device
Ripple.Arranging a boss 4 in the cavity of rectangular waveguide, described boss 4 has multi-stage stairs, and the number of step is by needs work
Bandwidth determine, bandwidth requirement is the widest, then step number just requires the most.In the present embodiment, boss 4 includes three steps, wherein
First order step is minimum, and afterbody step is the highest, and middle step increases successively.Have in the middle of this boss 4 one 90 degree turn
Kinking structure, first order step is right against the port direction of rectangular waveguide 1, and two-stage step is then turned round and turn 90 degrees just to needs together below
The narrow edge direction of axle head mouth output.Open a gap 5 at the top of afterbody step, be the weld part of coaxial port 2 inner core
Position, location when being used for welding coaxial connector inner core, the inner core of coaxial port is placed in this gap, then welds.Should be due to
Designing this gap, welding location is the most convenient, and easily location controls location tolerance.Described boss is to distance 6 He of Waveguide end face
Boss to the distance 7 of narrow limit, coaxial port 2 place end face, controls this distance at two and similarly helps to improve whole Waveguide coaxial
The echo of conversion equipment.
Fig. 2 is the simulation curve figure of described waveguide coaxial connecter device, and from simulation curve figure, the waveguide of this structure is same
Axle conversion equipment has the most excellent performance.
The above is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For any people being familiar with this technology and field thereof, without departing from this
On the premise of bright design, various deduction or change may be made, all should belong to this novel protection domain.
