Its performance has an important impact on the performance of the entire system.

[0003] In the use of ultra-wideband low-noise amplifiers, people frequently disassemble and assemble the interfaces and connectors. Doing so frequently easily causes the interfaces to become loose or even leads to the disconnection of the interfaces.
