Abstract

The invention discloses an aluminum oxide ceramic substrate 1W 13dB attenuation sheet which comprises a 2*3.5*0.635MM aluminum oxide substrate, wherein the back surface of the aluminum oxide substrate is printed with a back conducting layer, the front surface of the aluminum oxide substrate is printed with conductors and film resistors, and the conductors connect the film resistors to form a T-type attenuation circuit. The production of the attenuation sheet adopts high-temperature ceramic and paste co-sintering technology, so that the ceramic is metallized to generate circuit properties, thereby lowering the possible destructive influence of multiple-sintering on the product and reducing the failure risk in use. The attenuation sheet fully considers the performance indexes in the aspect of design, including resistance value precision, standing wave ratio and product power, and extends the series product line of 1W fixed film resistor-type attenuation sheets.

Description

technical field [0001] The invention relates to an alumina ceramic attenuation sheet, in particular to an attenuation sheet with an alumina ceramic substrate of 1 watt and 13dB. Background technique [0002] At present, the attenuator integrated with three film resistors is 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 power level on the high-frequency circuit, decoupling, and related The device plays a protective role. [0003] Since the research and development and manufacture of similar products in foreign countries started earlier than domestic ones, they are in an advantageous position both in product series and product characteristics. At the same time, the existing attenuators in the domestic market have low at...
