Embodiment
Below with reference to embodiment shown in the drawings, the utility model is described in detail.But these execution modes do not limit the utility model, the conversion in the structure that those of ordinary skill in the art makes according to these execution modes, method or function is all included in protection range of the present utility model.
Join Fig. 1 and Fig. 2, introduce the first embodiment of the utility model passive communication device 100.In the present embodiment, this passive communication device 100 comprises support body 11, communication guide rod 13 and supports isolating frame 14.
In present embodiment, this passive communication device 100 is mixer, in communications applications, often need the network signal of for example CDMA frequency range and GSM frequency range to close road output, now need to be applied to mixer the input/output signal of different frequency range is closed to road, avoided switching the trouble of different antennae, and can avoid the RF-coupled Intermodulation Interference causing between different channels.
Support body 11 has defined the monnolithic case of mixer, in it, definition has cavity 12, is provided with some resonant columns 111 in cavity 12, is also, cavity 12 and these resonant columns 111 have formed a cavity resonator jointly, are equivalent to the band pass filter of a high Q value, low differential loss.Wherein, on support body 11 inwalls, plating is provided with silver.
Communication guide rod 13 is for transmitting signal of communication, and this communication guide rod 13 is erected in cavity 12 by supporting isolating frame 14.In the present embodiment, this support isolating frame 14 adopts Polyetherimide material to make.Corresponding cooperation, support isolating frame 14 and adopt jetting formation process to make.
Polyetherimide claims again PEI resin, is the splendid thermoplastic engineering resin of a kind of stability.The operating ambient temperature of mixer is higher, and an outstanding properties of PEI resin is to stand long high temperature test, and this resistance to high-heat performance, adds the authentication in outstanding combustibility and UL laboratory, makes PEI resin meet the harsh requirement of high temperature application.And PEI resin has the ability that excellent anti-electromagnetic wave disturbs, and more adapts to the application of mixer with respect to the polytetrafluoroethylene of available technology adopting.
Meanwhile, support isolating frame of the prior art, owing to being to adopt polytetrafluoroethylene as raw material, in manufacturing process, need to be processed by the mode of pressurization or mold pressing, and efficiency is very low.And adopt PEI resin as the making material that supports isolating frame, can adopt efficiency higher ejection forming technique process, greatly enhance productivity.In actual raw material choose, support the ULTEM 1010 that isolating frame 14 adopts AM General company.
Communication guide rod 13 comprises a main part 131 and is connected to the some needle-like portion 132 on main part 131, and above-mentioned isolation bracing frame 14 comprises some support chips 141, and supports respectively corresponding in this main part 131 and some needle-like portion 132.In the present embodiment, this communication guide rod 13 is one-body molded.In concrete production technology, can for example a monoblock sheet material be carried out to punching press and make the required shape of communication guide rod 13, then on stamping forming communication guide rod 13, silver is established in plating, to meet the application demand of mixer.
Communication guide rod of the prior art, needle-like portion is generally fixed on main part by the mode of welding, and the hidden danger of doing is like this, because the operating ambient temperature of mixer is higher, needle-like portion and main part coupling part have the possibility of sealing-off, affect the normal work of mixer.And adopt one-body molded technology, can effectively avoid the generation of this kind of situation.
Join Fig. 3 and Fig. 4, introduce the second execution mode of the utility model passive communication device 200.In the present embodiment, this passive communication device 200 comprises support body 21, communication guide rod 23 and supports isolating frame 24.
