A coaxial frequency-separating connector of the present invention applies a first conducting element to receive a multi-frequency signal from a multi-frequency transmission element, and applies a multi-frequency dividing circuit to divide the multi-frequency signal to a plurality of different frequency signals such that the different frequency signals are respectively transmitted to the first coaxial cable and the second coaxial cable of a second conducting element. Furthermore, a first frequency contacting end to which a first RF element is connected and a second frequency contacting end to which a second RF element is connected are respectively connected on one end of the first coaxial cable and one end of the second coaxial cable. Accordingly, two RF elements with two different frequency bands can use only one coaxial frequency-separating connector to connect to a transmission element.
