For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the frequency division signal transceiver module structure chart of frequency division signal transmitter-receiverset set embodiment 1 of the present invention.Fig. 2 is the shielding case structure figure of frequency division signal transmitter-receiverset set embodiment 1 of the present invention.As depicted in figs. 1 and 2, this frequency division signal transmitter-receiverset set comprises frequency division signal transceiver module 10; Described frequency division signal transceiver module has signal receiving end 101, signal sending end 102, antenna end 103 and earth terminal 104;
In the inner (not shown) of frequency division signal transceiver module 10, described signal receiving end 101 is connected with described antenna end 103, for receiving the signal that described antenna end 103 receives; Described signal sending end 102 is connected with described antenna end 103, for sending signal by described antenna end 103; Described earth terminal 104 is for ground connection;
Described frequency division signal transmitter-receiverset set also comprises: the radome 20 comprising conductor composition; Described radome 20 ground connection, for shielding the signal of described signal sending end 102 transmission to the interference of the signal that described signal receiving end 101 receives; Described radome 20 is arranged on the periphery of described frequency division signal transceiver module 10, and described signal receiving end 101, signal sending end 102, is reserved with space between antenna end 103.
Frequency division signal transmitter-receiverset set in the present embodiment, owing to adopting radome, the transmitting terminal of frequency division signal transceiver module and the signal of receiving terminal are isolated, so the isolation of frequency division signal transmitter-receiverset set at the higher wave band of frequency can be improved, and then improve the sensitivity of frequency division signal transmitter-receiverset set.
It should be noted that, comprise the radome 20 of conductor composition, multiple way of realization can be had.Concrete, radome 20 can be an all-metal solid housing, also can be all-metal mesh casing; Can be add net metal line at insulating material to form radome, also can be in insulating material, add metal level form radome.As long as it will be apparent to those skilled in the art that and include conductor composition, there is the material of shield electromagnetic signals function, may be used to make radome.Because the conductivity of the conductor composition in radome is stronger, its shielding properties is also better, so, radome in the embodiment of the present invention, can preferentially select " metal base adds silver coating ", or " metal base adds Gold plated Layer ", or the material of other good conductivity.
In the present embodiment, described radome 20 is connected with described frequency division signal transceiver module 10 integral type; Concrete, described radome 20 comprises end 201 and sidewall 202; Described sidewall 202 is extended to form to described frequency division signal transceiver module 10 by described end 201.Described radome 20 is connected with described frequency division signal transceiver module 10 integral type, when can make actual production, radome 20 and described frequency division signal transceiver module 10 is integrally made.
In the present embodiment, space is reserved with between described radome 20 and described signal receiving end 101, signal sending end 102, antenna end 103, the implementation taked is: when the sidewall 202 of radome 20 extends to frequency division signal transceiver module 10, for the signal receiving end 101 of frequency division signal transceiver module 10, signal sending end 102, antenna end 103 and earth terminal 104, extend different length.For earth terminal 104, sidewall 202 directly extends to and is connected with described earth terminal 104, can realize the ground connection of radome 20 like this; For signal receiving end 101, signal sending end 102, antenna end 103, sidewall 202 extends to the top of described signal receiving end 101, signal sending end 102, antenna end 103, is no longer extending to each end from a distance with described signal receiving end 101, signal sending end 102, antenna end 103.Like this, in the region of signal receiving end 101, signal sending end 102, antenna end 103, space reserved between described radome 20 and described signal receiving end 101, signal sending end 102, antenna end 103 finally forms breach 203.
The object of breach 203 ensures that the signal receiving end 101 of frequency division signal transceiver module 10, signal sending end 102, antenna end 103 can normal transmitt or receive signals.According to the size of signal receiving end 101, signal sending end 102, antenna end 103, breach 203 also can be arranged to different size.In practical application, breach 203 can be designed to the rectangle matched with signal receiving end 101, signal sending end 102, antenna end 103 size.For rectangular indentation, what is called matches, just refer to one side that breach and signal receiving end 101 or signal sending end 102 or antenna end 103 are parallel, its width design is become substantially identical with the width of signal receiving end 101 or signal sending end 102 or antenna end 103.
The mode that radome 20 is connected with earth terminal also can have multiple.Concrete mode is different because of the difference of frequency division signal transceiver module.The difference of frequency division signal transceiver module is mainly the quantity of earth terminal.The contact point that radome is connected with earth terminal is more, and its shield effectiveness is better.For the frequency division signal transceiver module with more than 3 earth terminals, radome 20 can at least be connected with wherein 3 earth terminals.Preferably, the earth terminal be connected with radome 20, three earth terminals that preferably distance signal receiving terminal 101, signal sending end 102, antenna end 103 are nearest.
