Abstract: The present disclosure provides a filter and a radio frequency coaxial connector, to implement fast blind-mate of various signal ports. The filter includes: a filter cavity body and a coaxial connection component. The coaxial connection component is embedded in the filter cavity body in a self-clinching manner. The coaxial connection component includes a socket outer conductor and a main rod. The main rod penetrates the socket outer conductor, and one end of the main rod is connected to a signal end disposed in the filter cavity body. The coaxial connection component is in socket joint with a radio frequency coaxial connector by using the socket outer conductor, and the coaxial connection component matches the radio frequency coaxial connector.
