Description

technical field [0001] The invention relates to a broadband high-reliability coaxial-suspension coplanar waveguide switching device. Background technique [0002] In the field of aerospace, some small attenuators are often used to adjust the standing wave ratio of the microwave system or to achieve internal matching of the microwave system. This type of attenuator has a wide operating frequency band, high requirements on radio frequency indicators, and harsh environmental requirements. Therefore, it is necessary to design a high-reliability broadband attenuator. [0003] However, this type of attenuator needs to use a coplanar waveguide to coaxial transition device. Therefore, the quality of the coplanar waveguide to coaxial transition also affects the radio frequency performance index and high reliability of the attenuator. [0004] At present, most of these transfer devices are transfers from 2.4mm, 3.5mm, and 2.92mm coaxial to suspended coplanar waveguides, but mostly t...
