Description
technical field
The utility model relates to the design field of T/R assembly in Connectors for Active Phased Array Radar, particularly a kind of structure housing of T/R module.
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, Connectors for Active Phased Array Radar has become the developing main flow of radar.In every Connectors for Active Phased Array Radar, the T/R assembly that comprises multiple 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 receive path, increase if desired filter and be used for suppressing external interference signal, or in transmission channel, add filter, for suppressing interference signal to external world and other radio devices being caused to spectrum component and the high order harmonic component of interference.As the T/R assembly of one of Connectors for Active Phased Array Radar core component, along with modern science and technology is more and more higher to the requirement of Connectors for Active Phased Array Radar, therefore each performance of T/R assembly is also had higher requirement, T/R assembly requires high, the high conformity of integrated level, volume little, lightweight, can adapt to different workbenches and environment.
As shown in Figure 1, T/R radio-frequency module comprises the housing 1 for mounting circuit and functional module, housing 1 inside is welded with the heat pipe 2 that heat in module can be derived fast, housing 1 is made up of the symmetrical metal structure plate 3 of tow sides, the surface of structural slab 3 is furnished with the functional templates such as LTCC module 31, ripple control daughter board 32, high frequency substrate, and housing 1 is inner for being used for holding the hollow cavity of electronic devices and components and two probe Waveguide interfaces 34.When functional template is arranged on the surface of existing structure plate, because layout is unreasonable, cause space availability ratio low, then increased size and the weight of T/R radio-frequency module.
In the past because LTCC plate is ceramic material, can not adopt and be screwed, 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 structure plate, so, in the time of certain LTCC damaged template, inconvenience unloads maintenance by LTCC template from structural slab.Closely be fixed on the LTCC template on structural slab by conductive silver paste in addition, because the thermal coefficient of expansion between the two differs large (LTCC plate is that ceramic material, metal structure plate are aluminum alloy materials), under the impact of high low temperature operational environment, the solder side 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.
Utility model content
The purpose of this utility model is to overcome existing deficiency in prior art, and a kind of housing of T/R radio-frequency module is provided, and this housing can reasonably be arranged each functional template.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme:
A kind of housing of T/R radio-frequency module, described housing is made up of the symmetrical structural slab of tow sides, the surface of tow sides structural slab all has lightening grooves, enclosure interior is to hold the hollow cavity of electronic devices and components, the top on described structural slab surface has the draw-in groove of placing ripple control daughter board, the middle part on structural slab surface has the first mounting groove for pasting high frequency substrate, and the bottom on structural slab surface also has the second mounting groove for LTCC template is installed.
In the housing of above-mentioned T/R radio-frequency module, the top of described cavity is two probe waveguiding structures chambeies.
In the housing of above-mentioned T/R radio-frequency module, two probe waveguiding structures chamber that the top of described cavity comprises two close contacts, the convenient pair probe Waveguide interfaces of installing.
In the housing of above-mentioned T/R radio-frequency module, the housing general thickness of described T/R radio-frequency module is 10mm.
In the housing of above-mentioned T/R radio-frequency module, the second mounting groove region of described structural slab has screwed hole.
In the housing of above-mentioned T/R radio-frequency module, the aperture projection of described screwed hole, as the alignment pin that LTCC template is installed, can effectively improve the installation accuracy of LTCC template, and simplify installation process.
The mounting means of the utility model LTCC template on metal structure plate: in the back of LTCC template welding copper tungsten plate, adopt the mode of screw in compression copper tungsten plate that LTCC template is fixed on structural slab, LTCC template convenient disassembly, is convenient to LTCC template to carry out maintain and replace.Because the thermal coefficient of expansion of copper tungsten plate and LTCC template is almost identical, under high low temperature operational environment, the solder side 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 operational environment can not be restricted, LTCC template is not fragile yet.
compared with prior art, the beneficial effects of the utility model: the utility model reasonably arranges the second mounting groove that holds the draw-in groove of ripple control daughter board, the first mounting groove of pasting high frequency substrate, installation LTCC template by the surface at structural slab, make the surface of structural slab can reasonably arrange the each functional template of installation, and then reduced size and the weight of T/R radio-frequency module.On structural slab, have screwed hole for the second mounting groove region that LTCC template is installed, the convenient mode that adopts screw in compression copper tungsten plate is fixed to LTCC template on structural slab, so fixed form is convenient to LTCC template to carry out maintain and replace, and LTCC template is not fragile yet.
