The invention discloses an aluminium nitride ceramic attenuation sheet. The attenuation sheet includes a flange structure and a second lead. The flange structure is provided with a recessed groove, abolt fixed orifice and a ceramic fixed edge thereon, and the recessed groove is fixedly provided with a protruded fixed pole therein. The recessed groove is provided with the aluminium nitride ceramicbase body which is provided with a bottom plate and a fixed pore thereon. The bottom plate is fixedly provided with a first lead thereon. The rear parts of a resistor R1, a resistor R1, a resistor R3and a resistor R5 are all connected to a conductor. The aluminium nitride ceramic base body is covered with an aluminium nitride ceramic cap thereabove. The aluminium nitride ceramic cap is constituted by a cover plate and an edge strip. The aluminium nitride ceramic attenuation sheet herein is characterized by reasonable structure and configuration. Since a support conductor is configured, the resistors are separated, heat dissipation can be better carried out and the service lifetime of device elements are increased. And by adopting an epoxy resin protection film, the stability of the attenuation sheet is increased, and micro-wave regulation work can be better conducted. The aluminium nitride ceramic attenuation sheet herein can promote the development of radio frequency attenuation sheets.
Description
technical field [0001] The invention relates to the technical field of microwave radio frequency technology, in particular to an aluminum nitride ceramic attenuation sheet. Background technique [0002] Attenuation materials usually disperse semiconductor materials or easily polarized materials in the dielectric matrix, relying on the movement or swing of the charge carriers of the semiconductor materials or the dipoles of the polarized materials in the high-frequency field to consume high-frequency energy , Converted into heat energy and released. At present, multiple film resistors are integrated into one. Attenuators with different designs of resistors and circuits are widely used in aviation, aerospace, radar, radio, broadcast communication and other equipment fields. The use of a load chip can only simply consume and absorb excess power, while the use of an attenuator can absorb the reverse input power while extracting the required signal for analysis, and adjust the po...
