The narrow edge-grounded 150W load sheet of the high-power aluminum nitride ceramic substrate in the structure has good VSWR (voltage standing wave ratio) performance, the power on the 6.35*9.55*1mm aluminum nitride ceramic substrate can achieve 150W, and the property can simultaneously achieve 3G, thereby improving the power of the load sheet of the aluminum nitride ceramic substrate in the size to 150W on the premise of ensuring the excellent performances, enabling the range of applications of the aluminum nitride substrate in the size to be wider and being better matched with equipment.
Description
Technical field
The utility model relates to a kind of aluminium nitride ceramics substrate carrier sheet, the high-power aluminium nitride ceramics substrate 150 tile load sheets on particularly a kind of narrow edge joint ground.
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.Domestic aluminium nitride ceramics substrate carrier sheet all is the commercial communication field that is applied at present, and the commercial communication frequency requirement is in 3G and the 3G.For carrier sheet; Can reach the requirement of application; The one, need to satisfy high-power requirement, the one, characteristics of product just VSWR (standing-wave ratio) is more little good more, and the existing market basis needs to satisfy in 1.25: 1. along with increasing of frequency range; The VSWR of product also will be high more, so will realize that in the 3G band limits VSWR is little and reach 150W power.
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 superior aluminium nitride ceramics substrate carrier sheet of power-performance that can bear 150W.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The high-power aluminium nitride ceramics substrate 150 tile load sheets on a kind of narrow edge joint ground; It comprises the aluminium nitride substrate of a 6.35*9.55*1mm; 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: the high-power aluminium nitride ceramics substrate 150 tile load sheets on the narrow edge joint ground of this structure have good VSWR performance; The 2G frequency range reaches 1.05: 1 with interior standing-wave ratio; The 3G frequency range reaches 1.20: 1 with interior standing-wave ratio, and the power on the aluminium nitride ceramics substrate of 6.35*9.55*1.0mm reaches 150W.Having satisfied client's needs simultaneously laterally puts carrier sheet and carries out requirement of welding on equipment.
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.
