Radio frequency connector port with isolation function

A radio frequency connector port includes a connector body, a conductor unit and an isolator unit. The connector body is formed with a receiving space that extends in an axial direction. The conductor unit is disposed in the receiving space and extends in the axial direction. The isolator unit is disposed in the receiving space around the conductor unit, and includes a first capacitor, a second capacitor spaced apart from the first capacitor in the axial direction, and an inductor disposed between and coupled electrically to the first and second capacitors.
