PROBLEM TO BE SOLVED: To provide a low/high frequency separator on a coaxial line, which makes it possible to enhance a separation performance between low and high frequency signals, as well as a productivity. SOLUTION: The low/high frequency separator on a coaxial line includes a high band terminal 10 for transferring a high frequency signal, a low band terminal 20 for transferring a low frequency signal, and a mixing terminal 30 for transferring a mixing signal of the high and low frequency signals. It further includes a low pass filter 40 provided between the mixing terminal and the low band terminal for cutting off the high frequency signal and passing only the low frequency signal, a high pass filter 50 provided sequentially between the mixing terminal and the high band terminal for cutting off the low frequency signal and passing only the high frequency signal, and a band pass filter 60 for passing a high frequency signal of a bandwidth of 1.7 to 2.2 GHz. Thus, signal transfer of high quality can be carried out, and a high performance of separation between low and high frequency signals by the band bass filter can be assured, which makes it possible to minimize degradation of characteristics on the line or unfavorable effect on other components due to impedance mismatching.
