In an up converter equipped with a second mixer that mixes the obtained second local oscillation signal and the second intermediate frequency signal and outputs an RF signal, the first local oscillation signal is mixed with m (m is a natural number of 2 or more). ), a first bandpass filter that attenuates spurious components from the first multiplier, and an output from the first bandpass filter that is n(
a second multiplier that obtains the second local oscillation signal by multiplying the second local oscillation signal (n is a natural number greater than or equal to m); and a second bandpass filter that attenuates spurious components from the second multiplier. An up converter characterized by:
