Description
Technical field
The present invention relates to a kind of active phase array antenna, more particularly to a kind of active phase array antenna beam controlling system.
Background technology
T/R module wave control daughter board, wave are generally divided into the beam controlling system structure of active phase array antenna front-end product at present
Control distribution plate, wave control motherboard three parts.The wave control instruction that wave control motherboard reception antenna rear end is sent, by wave control motherboard
FPGA is distributed to by 4 one-to-one cables being connect with wave control distribution plate on wave control distribution plate again after resolving.Wave control distribution plate
It is distributed on T/R module wave control daughter board by the connector on plate again, realizes the various control functions to T/R module.
Beam controlling system structure in the prior art as shown in Figure 2, using such design, problem is, with wave control cable 3
The low-frequency connector being connected with T/R module wave control daughter board 2 on the wave control distribution plate 4 being connected is to be directly welded at wave control distribution
On plate 4, low-frequency connector is rigid connection each other with wave control distribution plate 4, then, when carrying out welding circuit board, interface
Between docking accuracy requirement it is very high, compare and be difficult to ensure.Moreover between wave control distribution plate 4 and T/R module wave control daughter board 2
Interface be also rigid connection, it is equally very high to positioning requirements, be not easy to ensure.Caused on wave control distribution plate 4 by the above reason
The low-frequency connector limited amount of welding（Typically now it is 4）.4 quantity of complete machine upper ripple control distribution plate is also unsuitable too many, generally
It it is 4, the low-frequency connector on such wave control motherboard 1 all is easier to operate in periphery.Final result results in active phase
Array antenna front port number cannot be too many, and the autgmentability of front is bad, and complete machine axial length can not be accomplished to minimize.
Invention content
It is an object of the invention to overcome to use wave control distribution plate in existing beam controlling system, lead to wave control distribution plate and a pair
It is rigid connection between one cable and T/R module wave control daughter board, causes excessively high to welding requirements, and is difficult to ensure the problem of requiring,
Cable is molded using a kind of wave control more than one point to which present invention offer is a kind of and replacing wave control distribution plate and one-to-one cable
Realize a kind of active phase array antenna beam controlling system of the normal transmission of wave control order.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes：
A kind of active phase array antenna beam controlling system, including：
Wave control motherboard, the wave control instruction sent for reception antenna rear end；
T/R module wave control daughter board realizes the wave control function to T/R module for receiving the wave control instruction；It further include wave control
It is molded cable, the molding cable connects the wave control motherboard and T/R module wave control daughter board, for sending out the wave control motherboard
Wave control instruction pass to the T/R module wave control daughter board.
Preferably, the cable that is molded one point includes a bus connecting pin and at least one separated time connecting pin more, described every
Port on one separated time connecting pin is attached according to port definition and the corresponding ports of the bus connecting pin, realizes signal
Transmission on the bus connecting pin and separated time connecting pin.
Preferably, the port number of the separated time connecting pin is 4.
Preferably, the bus connecting pin is 65 core structures, and 4 separated time connecting pins are 21 core structures.
Preferably, the bus connecting pin that cable is molded one point connects the wave control motherboard, the connection of separated time connecting pin more
The T/R module wave control daughter board.
Compared with prior art, beneficial effects of the present invention：It is substituted in original beam controlling system and is adopted with the mode that cable connects
With onboard interface docking connection mode, the welding difficulty substantially reduced and so that system installation operation become simple so that be
The T/R module expansions of system become more preferable, while reducing complete machine axial length.

Specific implementation mode
With reference to test example and specific implementation mode, the present invention is described in further detail.But this should not be understood
It is only limitted to embodiment below for the range of the above-mentioned theme of the present invention, it is all that this is belonged to based on the technology that the content of present invention is realized
The range of invention.
Embodiment 1
A kind of active phase array antenna beam controlling system, including：Wave control for the wave control instruction that reception antenna rear end is sent
Motherboard 1,1 surface of wave control motherboard are provided with 4 signal transmission interfaces 100；
Referring to Fig. 1 and Fig. 3, the bus connecting pin of each described signal transmission interface 100 connection wave control cable 3
300, and the other end of each wave control cable 3 is then 4 separated time connecting pins 310,4 separated time connecting pins 310
It is connect respectively with the T/R module wave control daughter board 2 of 1 lower section of wave control motherboard, and wave control signal is passed into the T/R module wave control daughter board
2, the T/R module wave control daughter board 2 makes corresponding control according to the wave control signal instruction received to T/R module.
Further, the bus connecting pin 300 is to be internally integrated 65 core wires, each described separated time connecting pin 310
On port be attached according to port definition and the corresponding ports of the bus connecting pin 300, and then obtain 4 21 core wires
The separated time connecting pin 310 of structure.
In conclusion one point of four molding made by using such a structure space shape according in machine product
Cable need to only be installed by corresponding position and be fixed, because comparatively cable is a flexible article, allowed in final assembly
A certain amount of deviation exists（Generally in +/- 2mm）, therefore contraposition when installation between cable and T/R module is of less demanding, it is whole in this way
Machine assembles the very simple and efficient of time-varying.
On the other hand, the axial length of complete machine is made to shorten 10mm or so after replacing wave control distribution plate 4 by using cable,
Tremendous contribution is made to the miniaturization of machine product.
Further, one point five or more of molding cable also can be used so that beam controlling system can integrate more TR moulds
Block meets the active phase array antenna complete machine structure requirement of big front multichannel.
