PROBLEM TO BE SOLVED: To provide a portable wireless transmission apparatus corresponding to a plurality of intermediate frequencies. SOLUTION: The portable wireless transmission apparatus includes an apparatus part wherein output-side units 1, 12 each for outputting a signal of an intermediate frequency and input-side units 3, 14 each for inputting a signal of an intermediate frequency are connected via cables 2, 13. In the portable wireless transmission apparatus, the output-side unit includes an output-side circuit corresponding to signals of a plurality of intermediate frequencies, an output-side determination means for determining an intermediate frequency on the basis of a signal input from the outside, and an output-side switching means for switching the output-side circuit so as to select the determined intermediate frequency, and the input-side unit includes an input-side circuit corresponding to signals of a plurality of intermediate frequencies, an input-side determination means for determining, on the basis of an input signal, an intermediate frequency included in the signal, and an input-side switching meas for switching the input-side circuit so as to select the determined intermediate frequency.
