Abstract
The utility model discloses a high power aluminium nitride ceramic substrate 150W load sheet which includes a 9.55*6.35*1.0mm aluminium nitride substrate. The back of the aluminium nitride substrate is printed with a back guide layer, and the front of the aluminium nitride substrate is printed with a resistor and a lead. The lead is connected with the resistor to form a load circuit. A ground terminal of the load circuit is electrically connected with the back guide layer. The resistor is printed with a glass protective film. The high power aluminium nitride ceramic substrate 150W load sheet of the above structure has an excellent VSWR performance, and can reach to a power of 150W on the 9.55*6.35*1.0mm aluminium nitride ceramic substrate and satisfy the 3G characteristics, so the application scope of the aluminium nitride ceramic substrate of the above size becomes wider, and the aluminium nitride ceramic substrate can match with a device preferably.
Description
Technical field
The utility model relates to a kind of aluminium nitride ceramics substrate carrier sheet, particularly a kind of high power aluminium nitride ceramics substrate 150 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.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 the requirement of power, the one, characteristics of product just VSWR (standing-wave ratio) is more little good more; The existing market basis needs to satisfy in 1.25: 1. and along with increasing of frequency range, the VSWR of product also will be high more.If VSWR is more little, with equipment mate just easy more, so when reaching the power of regulation, littler VSWR is the trend and the demand in market.
Simultaneously because the diversity requirement of design, with a kind of power product needed plurality of specifications is arranged, could satisfy client's various designing requirements like this.
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 150W, and standing wave needs to satisfy present 3G application requirements, reaches in 1.10: 1 with interior in the 2G frequency range simultaneously.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of high power aluminium nitride ceramics substrate 150 tile load sheets; It comprises the aluminium nitride substrate of a 9.55*6.35*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: the high power aluminium nitride ceramics substrate 150 tile load sheets of this structure have good VSWR performance; Power on the aluminium nitride ceramics substrate of 9.55*6.35*1.0mm reaches 150W; Make its characteristic standing wave can satisfy present 3G application requirements simultaneously; Reach in 1.10: 1 with interior in the 2G frequency range simultaneously, make the aluminium nitride ceramics substrate scope of application of this size wider, also can carry out good coupling with equipment more.
Adopt vertical design, structurally form complementation, satisfied the different design requirement of client with transverse design.
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.

Embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
As shown in Figure 1; These high power aluminium nitride ceramics substrate 150 tile load sheets comprise the aluminium nitride substrate 1 of a 9.55*6.35*1.0mm; The back up of aluminium nitride substrate 1 has back of the body conducting shell, and the front of aluminium nitride substrate 1 is printed with resistance 3 and lead 2, and lead 2 connects resistance 3 and forms load circuit; The earth terminal of load circuit is electrically connected through the silver slurry with back of the body conducting shell, thereby makes the load circuit earth-continuity.Back of the body conducting shell and lead 2 are formed by the conductive silver paste printing, and resistance 3 is formed by the resistance slurry printing.Be printed with glass protection film 4 on the resistance 3.The upper surface of lead 2 and glass protection film 4 also is printed with one deck black protective film 5.
The high power aluminium nitride ceramics substrate 150 tile load sheets of this this structure have good VSWR performance; Power on the aluminium nitride ceramics substrate of 9.55*6.35*1.0mm reaches 150W; Make its characteristic standing wave can satisfy present 3G application requirements simultaneously; Reach in 1.10: 1 with interior in the 2G frequency range simultaneously, make the aluminium nitride ceramics substrate scope of application of this size wider, also can carry out good coupling with equipment more.Power according to this aluminium nitride ceramics substrate carrier sheet of detection can be born is highly stable, can reach the requirement that communication period absorbs required power fully.
Adopt vertical design, structurally form complementation, satisfied the different design requirement of client with transverse design.
More than a kind of high power aluminium nitride ceramics substrate 150 tile load sheets that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection range of the utility model.
