[0002] Coaxial attenuator is an energy loss RF / microwave component with resistive material inside. In addition to the commonly used resistive fixed attenuator, there is also an electronically controlled fast adjustment attenuator. Attenuators are widely used in various occasions where power level adjustment is required.

[0003] At present, when the existing coaxial attenuator is used, the components used for the coaxial attenuator are usually integrated and concentrated inside the heat dissipation component to form an integrated coaxial attenuator. During the long-term use of this integrated coaxial attenuator, the heat dissipation component is easily shaken and affects the heat dissipation effect of the integrated coaxial attenuator. At the same time, when installing the existing coaxial attenuator, it is necessary to tighten and adjust the external screw sleeve, which is time-consuming and labor-intensive and inconvenient to install and disassemble.

[0004] To this end, in response to the above problems, we propose an integrated microwave RF coaxial attenuator to solve the above problems. Utility Model Content
