Abstract
In a frequency converter, a transmission signal having a first frequency component and a second frequency component is multiplied by a local signal, to thereby frequency-convert the transmission signal. In a power amplifier, the frequency-converted transmission signal is amplified. A demultiplexing circuit generates a first transmission signal and a second transmission signal from the amplified transmission signal. A controller is configured to set for a transmission section a frequency set suitable for two irradiation frequencies.
