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.
At present to reach 150 tile load sheets a kind of be to select the BeO material for use to state's internal power, and this material is poisonous, is easy in process of production environment is polluted, and producers healthy brought certain harm.Another kind is to use the aluminium nitride substrate (substrate size is 9.55*6.35*1mm) of large-size, and this large-sized aluminium nitride substrate does not satisfy the requirement of current base station miniaturization.Present domestic aluminium nitride substrate can only be made the carrier sheet that can bear 100W power on the size of 8.7*5.9*1mm.
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 carrier sheet that can on the 8.7*5.9*1mm substrate, carry 150W power.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of impedance is the high-power aluminium nitride ceramics substrate 150 tile load sheets of 50 Ω; It comprises the aluminium nitride substrate of a 8.7*5.9*1mm; The front of said aluminium nitride substrate is printed with 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, said resistance transverse arrangement of turbo.
Preferably, the pad of said load circuit is provided with Gold plated Layer.
