Environment-friendly ceramic 10 W 13 dB attenuation piece

Abstract

The invention discloses an environment-friendly ceramic 10 W 13 dB attenuation piece. The environment-friendly ceramic 10 W 13 dB attenuation piece comprises a substrate made of environment-friendly ALN materials. The size of the substrate made of the ALN materials is 2.5 mm * 5 mm * 1 mm, high-temperature silver paste wires are printed on the front face of the substrate made of the ALN materials, film-shaped resistors are printed between the high-temperature silver paste wires, the high-temperature silver paste wires and the film-shaped resistors are communicated through high-temperature sintering, a conductor layer is printed on the back face of the aluminum nitride ceramic substrate, and the high-temperature silver paste wires and the back conductor layer are communicated through secondary printing silver paste on the side face. According to the attenuation piece, in scheme design, toxic BeO materials are replaced by the environment-friendly ALN materials, meanwhile, the size of the product is reduced as much as possible on the premise that power requirements are met, the production efficiency of the product is improved, and material cost is reduced; in circuit design, the requirements for the VSWR, attenuation accuracy and other performance indexes on an existing market are fully considered, the gap that no small-size attenuation piece is available in China is filled in, the application requirements of an existing mainstream 3G network are met, and various indexes can reach the international advanced level.

Description

technical field [0001] The invention relates to a ceramic attenuator, in particular to an environment-friendly ceramic 10-watt 13dB attenuator. Background technique [0002] Attenuators play an irreplaceable role in aviation, aerospace, radar, radio, broadcasting, communications and other fields. Most of the equipment used load plates to absorb power, and load plates can only simply consume and absorb excess power. is a pure power dissipating device. The use of the attenuator can also sample and analyze the working signal of the equipment while absorbing the reverse input power, which can not only protect the equipment, but also detect the equipment. [0003] With the continuous advancement of science and technology, the requirements for communication equipment are getting higher and higher. At present, many communication equipment, such as base stations for receiving and transmitting signals of our mobile phones, are increasingly using attenuators. In foreign countries, e...

Problems solved by technology

[0004] At present, high-power attenuators mostly use toxic BeO material as the substrate material, but it will produce a lot of toxic dust during laser trimming, which is harmful to the body.
