    摘要: According to an embodiment, a frequency converting device is provided with a duty adjusting unit that generates a 1/N local signal, which is a local signal with a duty ratio of 1/N, when N is an integral number not smaller than 3 and an N-th high-frequency component included in the local signal is a target of inhibition. Further, this is provided with a mixer that outputs difference or sum between/of the 1/N local signal and an input signal.
