For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the frequency division signal transceiver module structure chart of frequency division signal R-T unit embodiment 1 of the present invention.Fig. 2 is the shielding case structure figure of frequency division signal R-T unit embodiment 1 of the present invention.As depicted in figs. 1 and 2, this frequency division signal R-T unit 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, is used for receiving the signal that described antenna end 103 receives; Described signal sending end 102 is connected with described antenna end 103, is used for by described antenna end 103 transmitted signals; Described earth terminal 104 is used for ground connection;
Described frequency division signal R-T unit also comprises: the radome 20 that comprises the conductor composition; Described radome 20 ground connection are used for shielding the signal of described signal sending end 102 transmissions to the interference of the signal of described signal receiving end 101 receptions; Described radome 20 is arranged on the periphery of described frequency division signal transceiver module 10, and is reserved with the space between described signal receiving end 101, signal sending end 102, antenna end 103.
Frequency division signal R-T unit 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 can improve the frequency division signal R-T unit at the isolation of the higher wave band of frequency, and then improve the sensitivity of frequency division signal R-T unit.
Need to prove, comprise the radome 20 of conductor composition, multiple way of realization can be arranged.Concrete, radome 20 can be an all-metal solid housing, can be also all-metal mesh casing; Can be to add the net metal line at insulating material to form radome, can be also to add metal level to form radome in insulating material.It will be apparent to those skilled in the art that to have the material of shield electromagnetic signals function so long as include the conductor composition, 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 ", perhaps " metal base adds Gold plated Layer ", the perhaps material of other good conductivity.
In the present embodiment, described radome 20 is connected with described frequency division signal transceiver module 10 integral types; 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 types, can so that during actual production, radome 20 and described frequency division signal transceiver module 10 be done as a whole the making.
In the present embodiment, be reserved with the space between described radome 20 and described signal receiving end 101, signal sending end 102, antenna end 103, the implementation of taking is: when the sidewall 202 of radome 20 extends to frequency division signal transceiver module 10, signal receiving end 101, signal sending end 102, antenna end 103 and earth terminal 104 for frequency division signal transceiver module 10 extend different length.For earth terminal 104, sidewall 202 directly extends to described earth terminal 104 and is connected, and can realize like this ground connection of radome 20; 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 zone of signal receiving end 101, signal sending end 102, antenna end 103, the space of reserving between described radome 20 and described signal receiving end 101, signal sending end 102, antenna end 103 finally forms breach 203.
