Description
Technical field
The present invention relates in Connectors for Active Phased Array Radar t/r assembly design field, particularly to a kind of ltcc assembly
Installation module with structural cavity body composition.
Background technology
Since the radar appearance thirties in 20th century, Radar Technology obtains high speed development in World War II,
After the nineties, Connectors for Active Phased Array Radar has become the developing main flow of radar.In every Connectors for Active Phased Array Radar, comprise multiple
The t/r assembly of quantity, it had not only completed reception task but also had completed launch mission, also carried out phasescan to antenna.Each t/r group
Part is equivalent to the tuner of an ordinary radar, has both included emission power amplifier, has low-noise amplifier, phase shifter again
And the functional circuit such as Beam steering circuit, wave filter can be increased if necessary in receiving channel and be used for suppressing external interference signal,
Or in transmission channel plus wave filter, may interference signal and other radio devices are interfered to external world for suppression
Spectrum component and higher hamonic wave.As the t/r assembly of one of Connectors for Active Phased Array Radar core component, with modern science and technology to active
The requirement more and more higher of phased-array radar, therefore it is also proposed higher requirement to each performance of t/r assembly, and t/r assembly will
Ask that integrated level is high, concordance is good, small volume, lightweight, adapt to different work platformses and environment.
As shown in Figure 1, t/r radio-frequency module includes the structural cavity body 1 for installing circuit and functional module, structural cavity body
Being welded with inside 1 can be by quick for heat in the module heat pipe derived, and structural cavity body 1 is by the symmetrical metal structure of tow sides
Plate 11 forms, and the surface layout of structural slab 11 has the functional templates such as ltcc module, ripple control daughter board, high frequency substrate, in structural cavity body 1
Portion is the hollow cavity for accommodating electronic devices and components and double probe Waveguide interface.
Existing ltcc module is generally ceramic material and makes it is impossible to be fixed on structural slab using screw, screw
Easily ltcc plate is damaged by pressure if fixation, therefore generally using conductive silver paste, ltcc template is affixed directly on metal structure plate,
So when certain ltcc damaged template it has not been convenient to ltcc template is taken off maintenance from structural slab.Additionally by conductive silver paste
It is tightly fixed to the ltcc template on structural slab, (ltcc plate is ceramic material because thermal coefficient of expansion difference therebetween is larger
Material, metal structure plate are aluminum alloy materials), under the influence of high/low temperature working environment, the solder side of the two easily ftractures, and leads to
Ltcc template comes off from structural slab；And the deformation of ltcc template cannot effectively discharge, ltcc template also easily occurs disconnected
Split, lead to ltcc damaged template.
Content of the invention
It is an object of the invention to overcoming the ltcc module being arranged in prior art on structural cavity body to there is dismounting not side
Just, the flimsy deficiency of ltcc module, provides the installation module of a kind of ltcc assembly and structural cavity body composition.
In order to realize foregoing invention purpose, the invention provides technical scheme below:
The installation module that ltcc assembly is formed with structural cavity body, including structural cavity body and ltcc assembly, described structural cavity body
It is made up of the symmetrical structural slab of tow sides, the bottom of structure plate surface has the mounting groove for installing ltcc assembly,
Mounting groove region has screwed hole, and the aperture of described screwed hole is raised；Described ltcc assembly includes ltcc template and is welded on
The copper tungsten plate at ltcc template back, the edge of described ltcc assembly has installing hole, and described installing hole semicircular in shape, in copper tungsten plate
Install pore radius little compared with the installation pore radius in ltcc template, by the way of screw in compression copper tungsten plate, ltcc assembly is fixed
Installation groove location on structural slab.
In the installation module that above-mentioned ltcc assembly is formed with structural cavity body, the surface of tow sides structural slab all has loss of weight
Groove, for accommodating the hollow cavity of electronic devices and components inside structural cavity body.
In the installation module that above-mentioned ltcc assembly is formed with structural cavity body, the left and right edges of described ltcc assembly respectively have
Two installing holes.
In the installation module that above-mentioned ltcc assembly is formed with structural cavity body, described ltcc template is made up of ceramic material.
Ltcc assembly of the present invention is in the mounting means on metal structure plate: by ltcc by the way of screw in compression copper tungsten plate
Assembly is fixed on structural slab, ltcc assembly convenient disassembly, is easy to ltcc assembly is carried out with maintenance replacing.Due to copper tungsten plate with
The thermal coefficient of expansion of ltcc template is almost identical, and under high/low temperature working environment, the solder side of the two is not easily susceptible to cracking；And tungsten copper
Each other small due to using screw mounting means, there is certain interval between plate and structural slab, under high/low temperature working environment
Expand/shrink and can not be limited, ltcc template is not easy to damage.
Compared with prior art, beneficial effects of the present invention: the installation module of the present invention includes structural cavity body and ltcc group
Part, due to the modular construction plate of structural cavity body, the mounting groove region that its surface is used for installing ltcc assembly has screwed hole；
In addition weld, at the back of ltcc template, the ltcc assembly that copper tungsten plate is constituted, its edge also has installing hole, this installing hole is in half
Installation pore radius in circle, and copper tungsten plate is little compared with the installation pore radius in ltcc template.By opening up screwed hole in structural slab
And open up unique installing hole on ltcc assembly, then by the way of screw in compression copper tungsten plate, ltcc assembly is fixed to knot
Installation groove location on structure plate, such fixed form is easy to ltcc template is carried out with maintenance replacing, and ltcc template is not easy to damage；
Copper tungsten plate is almost identical with ltcc template thermal coefficient of expansion, and under high/low temperature working environment, the solder side of the two is not easily susceptible to cracking；And
And due to using screw mounting means, there is certain interval between copper tungsten plate and structural slab, under high/low temperature working environment each other
Small expansion/contraction can not be limited, ltcc template be not easy to damage.
