Problems solved by technology

Under normal circumstances, it is very difficult to achieve a coaxial fixed attenuator for 18-40GHz high frequency. It is also necessary to use a T-shaped thick film circuit attenuator made of beryllium oxide ceramic substrate, and it must be made into DC-18GHz high frequency at the same time. Coaxial fixed attenuators that handle 250 watts are even more difficult

Abstract

The invention discloses a 250W power 18GHz fixed attenuator comprising a plurality of identical attenuation slice components arranged in turn, wherein a connecting member is connected between each of the two adjacent attenuator slice components; a male connector component connected with the attenuation slice component located on the leftmost side in a matched mode; and a female connector component connected to the rightmost attenuation slide component in a matched mode. According to the 250W power 18GHz fixed attenuator, standing waves are small; the frequency band is wide; the product working frequency band ranges from direct currents to 18GHz; the power capacity is 250W; a good rapid heat radiation capability is provided; the mechanical stability is high; and the repeatability is high.

Description

technical field [0001] The invention relates to the field of microwave passive devices, in particular to a high-efficiency fixed attenuator with 250W power and 18GHz. Background technique [0002] The coaxial fixed attenuator is a kind of microwave component, which is widely used in microwave communication, radar and other equipment. The coaxial fixed attenuator must meet the electrical and mechanical performance requirements of the system, and at the same time, it must be simple and efficient in mass production. High pass rate and low production cost. The coaxial fixed attenuator is composed of a connector and an attenuator. The connector includes two parts: a female connector and a male connector. Under normal circumstances, it is very difficult to achieve a coaxial fixed attenuator for 18-40GHz high frequency. It is also necessary to use a T-shaped thick film circuit attenuator made of beryllium oxide ceramic substrate, and it must be made into DC-18GHz high frequency at...
