Embodiment
Below in conjunction with accompanying drawing 1 to 5, the mixer that the utility model embodiment is provided carries out detailed elaboration.
Shown in above-mentioned accompanying drawing 1-5, the mixer that the utility model embodiment provides can be formed 02 by a cavity 01, a single-clad board (PCB) 10 and a cover plate and form.
In the present embodiment; Like accompanying drawing 1,3, shown in 4; On two sidewalls in opposite directions of cavity 01, can be respectively arranged with holder 03,04,05, and holder 03,04 is arranged on the same sidewall; Holder 05 then is arranged on another relative sidewall; Radio frequency cable covers the etched metallic conductor band line 08 of copper face with radio-frequency cable inner conductor with single face PCB10 and is fixedly connected through modes such as welding after passing respectively and being used for holder 03,04,05 that signal inputs or outputs, and radio frequency cable outer conductor and holder 03,04,05 are fixedly connected through modes such as welding.Be that the present embodiment feeding classification is from cavity 01 two sides feed, that is to say that the sense of current of the signal that inputs or outputs this mixer is parallel to metallic conductor band line 08.When from holder 05 end input broadband signal; Holder 03 and the irrelevant narrow band signal of 04 end output two-way, among this embodiment, holder 04 end is compared the exportable high-frequency signal of holder 03 end; The exportable low frequency signal of holder 03 end, two-way output Signal Spacing degree＜-32dB; When from holder 03 and 04 end input two-way narrow band signal, can be from holder 05 end output one band signal of having a lot of social connections.
In the present embodiment; Places, four angles of cavity 01 upper surface (being four edges of sidewall) but integrated molding has four boss 06, be used for supporting and securing cover plate 02, when cover plate 02 through boss 06 and after cavity 01 is fixedly connected; Except that four fixed angles, remainder is suspended in cavity 01 upper surface.
In the present embodiment, the bottom of cavity 01 also can be provided with fixing hole 07, is used to realize that single face PCB10's is fixing.
In the present embodiment, metallic conductor band line 08 is etched in the copper face that covers of single face PCB10, and single face PCB10 does not cover copper face and can fit promptly tangent with cavity 01 bottom surface.Because in the present embodiment; Medium through high dielectric constant is the support of single face PCB10 as the signal transmission, thereby when guaranteeing signal quality, reduces the electric size of mixer; And then realize the miniaturization Design of mixer, reduce the weight and volume of mixer.After the weight and volume of mixer reduces; The weight of smart antenna is further reduced; Also can make and place more mixer in the smart antenna; Be example for example with conventional 8 port smart antennas, can integrated side by side at least 8 mixers that the utility model embodiment provides, and the weight of smart antenna does not have increase.
In the present embodiment, on single face PCB10, also can be provided with location hole 09, this location hole 09 is corresponding with the fixing hole 07 that cavity bottom is provided with, the bottom that is used to realize single face PCB10 is fixedly connected on cavity 01.
In the present embodiment, cover plate 2 can be a metal cover board, and can be provided with fixing hole equally, and is corresponding with boss 06, and realization is the upper end with the openend that cover plate 2 is fixedly connected on cavity 01, thereby realizes the covering to cavity 01.
Can find out that from the above the mixer that the utility model provides is devoted to solve the volume and the weight of mixer; At the circuit side connector face, need not transitional link, can directly be connected with radio frequency cable; Cavity and metallic conductor band line are processed equal disposal molding, need not debugging, ease of assembly.And; The mixer that the utility model embodiment provides has characteristics such as volume is little, in light weight, signal quality is good, when concrete the application, can a plurality of these mixers be integrated in antenna; Be arranged side by side in antenna inside; Minimum distance is less than 2mm in twos, and no signal is disturbed between any two, and just integrated each mixer index of back and single mixer can be consistent in desirable environmental testing index.
The above only is the execution mode of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
