Example Embodiment

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the 100-watt 6dB attenuator of the aluminum nitride ceramic substrate includes an aluminum nitride substrate 1, a conductive layer is printed on the back of the aluminum nitride substrate 1, and the conductive layer is printed by printing silver paste. The front surface of the aluminum nitride substrate 1 is printed with resistors R1, R2, R3, R4, R5 and silver paste wires 2. The silver paste wires 2 connect the resistors R1, R2, R3, R4, R5 to form an attenuation circuit with a TT structure. A glass protective film 3 is printed on the resistors R1, R2, R3, R4, and R5, and the glass protective film 3 is used to protect the resistors R1, R2, R3, R4, R5. A black protective film 4 is also printed on the upper surface of the entire circuit, namely the silver paste wire 2 and the glass protective film 3, and a bla...

Abstract

The invention discloses an aluminum nitride ceramic substrate 100 W-6 dB attenuation slice. The attenuation slice comprises an 8.9 mm*5.7 mm*1 mm aluminum nitride ceramic substrate. A silver paste conductor layer is printed on the back surface of the aluminum nitride ceramic substrate, silver paste wires are printed on the front surface of the aluminum nitride ceramic substrate, the two ends of each silver paste wire are respectively connected with a bonding pad, resistors are printed among the silver paste wires, high-temperature protection films are printed on the resistors, and acid and alkali-resistant protection films are printed on the silver paste wires and the high-temperature protection films. According to the attenuation slice, in the design thought, the circuit structure of the output end is optimized, standing waves of the output end are improved, and the inductance-capacitance performance of circuits is adjusted. Meanwhile, by accurate modification of the resistance value, the high-accuracy attenuation value is obtained. Various indexes of the aluminum nitride ceramic substrate 100 W-6 dB attenuation slice are good, and therefore the aluminum nitride ceramic substrate 100 W-6 dB attenuation slice meets the use requirements of present 4G networks.

Description

technical field [0001] The invention relates to an aluminum nitride ceramic substrate attenuation sheet, in particular to a 100-watt 6dB attenuation sheet for an aluminum nitride ceramic substrate. Background technique [0002] At present, most communication base stations use high-power ceramic load chips to absorb the reverse input power of communication components. High-power ceramic load chips can only simply consume and absorb excess power, but cannot monitor the working conditions of the base station in real time. When the base station fails, it cannot make a timely judgment and has no protective effect on the equipment. The attenuation sheet can not only absorb the reverse input power of the communication components in the communication base station, but also extract part of the signal in the communication components, and monitor the base station in real time, thus forming an effective protection for the equipment. [0003] As a power consumption component, the attenu...
