A noise suppression apparatus is provided with: an offset correction unit that corrects changes in a DC offset generated by the hopping of radio frequencies or a local leak correction unit that corrects changes of local leaks generated by hopping of radio frequencies; and a noise elimination unit that suppresses the amplitude of noise generated by the offset correction unit or local leak correction unit and that is provided with switches that turn ON and OFF in synchronization with the hopping of radio frequencies, and an amplitude suppression unit connected between two differential output lines of the offset correction unit or the local leak correction unit by way of the switches. |
