Description
Technical field
The present invention relates to the design field of T/R assembly in Active Phased Array Radar, the installation module that particularly a kind of LTCC assembly and structural cavity body form.
Background technology
Since the thirties in 20th century, radar came out, Radar Technology has obtained high speed development in World War II, and after the nineties, Active Phased Array Radar has become the developing main flow of radar.In every Active Phased Array Radar, the T/R assembly that comprises a plurality of quantity, it not only completes reception task but also completes launch mission, also antenna is carried out to phasescan.Each T/R assembly is just equivalent to the tuner of an ordinary radar, both included emission power amplifier, there are again the functional circuits such as low noise amplifier, phase shifter and wave beam control circuit, can in receiving cable, increase if desired wave filter and be used for suppressing external interference signal, or in transmission channel, add wave filter, for suppressing undesired signal to external world and other radio devices being caused to spectrum component and the higher hamonic wave of interference.T/R assembly as one of Active Phased Array Radar core component, along with modern science and technology is more and more higher to the requirement of Active Phased Array Radar, therefore each performance of T/R assembly is also had higher requirement, T/R assembly requires that integrated level is high, high conformity, volume are little, lightweight, can adapt to different workbenches and environment.
As shown in Figure 1, T/R radio-frequency module comprises the structural cavity body 1 for mounting circuit and functional module, structural cavity body 1 inside is welded with the heat pipe that heat in module can be derived fast, structural cavity body 1 is comprised of the symmetrical metal construction plate 11 of tow sides, the surface of structural slab 11 is furnished with the functional templates such as LTCC module, ripple control daughter board, high frequency substrate, and structural cavity body 1 is inner for being used for holding the hollow cavity of electronic devices and components and two probe Waveguide interfaces.
Existing LTCC module is generally stupalith and makes, can not adopt screw to be fixed on structural slab, the fixing words of screw are easily damaged LTCC plate by pressure, therefore conventionally adopt conductive silver paste that LTCC template is directly sticked on metal construction plate, so, when certain LTCC damaged template, inconvenience is taken off maintenance by LTCC template from structural slab.By conductive silver paste, be closely fixed on the LTCC template on structural slab in addition, because the thermal expansivity between the two differs large (LTCC plate is that stupalith, metal construction plate are aluminum alloy materials), under the impact of high low temperature working environment, the face of weld of the two easily ftractures, and causes LTCC template to come off from structural slab; And the deformation of LTCC template can not get effective release, also easily there is fracture in LTCC template, causes LTCC damaged template.
Summary of the invention
The object of the invention is to overcome the LTCC module being arranged on structural cavity body in prior art and exist dismounting inconvenient, the flimsy deficiency of LTCC module, the installation module that provides a kind of LTCC assembly and structural cavity body to form.
In order to realize foregoing invention object, the invention provides following technical scheme:
The installation module that LTCC assembly and structural cavity body form, comprise structural cavity body and LTCC assembly, described structural cavity body is comprised of the symmetrical structural slab of tow sides, the bottom on structural slab surface has for the mounting groove of LTCC assembly is installed, mounting groove region has threaded hole, the aperture projection of described threaded hole; Described LTCC assembly comprises LTCC template and is welded on the copper tungsten plate at LTCC template back, the edge of described LTCC assembly has mounting hole, described mounting hole semicircular in shape, mounting hole radius in copper tungsten plate is little compared with the mounting hole radius in LTCC template, adopts the mode of screw in compression copper tungsten plate that LTCC assembly is fixed to the mounting groove position on structural slab.
In the installation module that above-mentioned LTCC assembly and structural cavity body form, the surface of tow sides structural slab all has lightening grooves, and structural cavity body is inner for holding the hollow cavity of electronic devices and components.
In the installation module that above-mentioned LTCC assembly and structural cavity body form, the left and right edges of described LTCC assembly respectively have two mounting holes.
In the installation module that above-mentioned LTCC assembly and structural cavity body form, described LTCC template is that stupalith is made.
The mounting means of LTCC assembly of the present invention on metal construction plate: adopt the mode of screw in compression copper tungsten plate that LTCC assembly is fixed on structural slab, LTCC assembly convenient disassembly, is convenient to LTCC assembly to carry out maintain and replace.Because the thermal expansivity of copper tungsten plate and LTCC template is almost identical, under high low temperature working environment, the face of weld of the two is not easy cracking; And between copper tungsten plate and structural slab owing to adopting screw mounting means, there is certain interval, the small expansion/contraction each other under high low temperature working environment can not be restricted, LTCC template is not fragile yet.
compared with prior art, beneficial effect of the present invention: installation module of the present invention comprises structural cavity body and LTCC assembly, and due to the assembly of structural cavity body---structural slab, its surface has threaded hole for the mounting groove region of LTCC assembly is installed; The LTCC assembly forming in the back of LTCC template welding copper tungsten plate in addition, its edge also has mounting hole, this mounting hole semicircular in shape, and the mounting hole radius in copper tungsten plate is little compared with the mounting hole radius in LTCC template.By offering threaded hole at structural slab and offer unique mounting hole on LTCC assembly, adopt again the mode of screw in compression copper tungsten plate that LTCC assembly is fixed to the mounting groove position on structural slab, so fixed form is convenient to LTCC template to carry out maintain and replace, and LTCC template is not fragile yet; Copper tungsten plate and LTCC template thermal expansivity are almost identical, and under high low temperature working environment, the face of weld of the two is not easy cracking; And between copper tungsten plate and structural slab owing to adopting screw mounting means, there is certain interval, the small expansion/contraction each other under high low temperature working environment can not be restricted, LTCC template is not fragile yet.
