Abstract

The invention discloses a 1-watt 18dB attenuation sheet of an aluminum oxide ceramic substrate, which comprises an aluminum oxide substrate, wherein a back face of the aluminum oxide substrate is printed with high-temperature conductive silver pulp, a front face of the aluminum oxide substrate is printed with two pads, the pads are respectively connected with a guide line, the guide lines are connected via membrane-shaped resistors, and the resistors are arranged in parallel and in series to form an attenuation circuit. On a design, power bearing capability is fully considered, the 1-watt 18dB attenuation sheet of the aluminum oxide ceramic substrate is a type of matching a capacitor and an inductor, has high frequency and no induction, and can be applied to three generation (3G) frequency ranges.

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 18dB. 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 features. At the same time, the existing attenuators in the domestic market have low attenuati...
