Simultaneously, characteristics of the loading piece break through 3G and reach 4G, so that the small-size aluminum nitride ceramic substrate is wider in use range and can be better matched with equipment.
Description
Technical field
The utility model relates to a kind of aluminium nitride ceramics substrate carrier sheet, and particularly a kind of impedance is 50 Ω small size aluminium nitride ceramics substrates, 100 tile load sheets.
Background technology
Aluminium nitride ceramics substrate carrier sheet is mainly used in the power that in communication base station, absorbs reverse input in the communication component, if can not bear the power of requirement, load will burn out, and possibly cause entire equipment to burn out.Present most of communication base station all is that utilizing high power pottery carrier sheet absorbs reverse input power in the communication component, requires basic size more and more littler, and needs power absorbed increasing; Characteristics of product just VSWR (standing-wave ratio) is more little good more, and market value basis need satisfy in 1.25: 1. and along with increasing of frequency range, the VSWR of product also will be high more. and at present domestic carrier sheet VSWR reaches requirement at 3G with interior; There is minority can reach 3G; But along with the continuous development of communication network, to frequency range require increasingly high, so size is more little; The frequency range that can reach is high more, is the direction of development.
The utility model content
To the deficiency of above-mentioned prior art, the technical problem that the utility model will solve provides a kind of power that can bear 100W, and standing-wave ratio need reach the aluminium nitride ceramics substrate carrier sheet that 4G and 4G can be applied with interior frequency range.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of impedance is 50 Ω small size aluminium nitride ceramics substrates, 100 tile load sheets; It comprises the aluminium nitride substrate of a 6.0*6.0*1.0mm; The back up of said aluminium nitride substrate has back of the body conducting shell, and the front of said aluminium nitride substrate is printed with resistance and lead, and said lead connects said resistance and forms load circuit; The earth terminal of said load circuit is electrically connected with said back of the body conducting shell, is printed with glass protection film on the said resistance.
Preferably, the upper surface of said lead and glass protection film also is printed with one deck black protective film.
Preferably, said back of the body conducting shell and lead are formed by the conductive silver paste printing, and said resistance is formed by the resistance slurry printing.
Technique scheme has following beneficial effect: this structure is enterprising one-step optimization on original design basis; 100 watts the power requirement of on littler size, realizing; Meet the miniaturization development trend in components and parts field, and then enlarged the application of product.The impedance of this structure is that 50 Ω aluminium nitride ceramics substrates, 100 tile load sheets have good VSWR performance; Power on the aluminium nitride ceramics substrate of 6.0*6.0*1.0mm reaches 100W; Make its characteristic break through 3G simultaneously; Reach 4G, made the aluminium nitride ceramics substrate scope of application of this size wider, also can carry out good coupling with equipment more.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
