Claim Text:
1. A radio device configured to perform upsampling on a forward wave containing a first signal and a second signal to broaden a processing band to a transmission band, then amplifying the forward wave using an amplifier, and transmitting the forward wave, the radio device comprising: a first calculator that calculates the power of a first component corresponding to the first signal of the transmission band from among the forward wave when the power of the first signal is larger than the power of the second signal and calculates the power of the first component corresponding to the second signal of the transmission band from among the forward wave when the power of the first signal is less than the power of the second signal; a second calculator that calculates the power of a second component corresponding to a part of the transmission band from among a reflected wave from the antenna toward the amplifier, a frequency of the second component being same as a frequency of the first component; a third calculator that calculates a voltage standing wave ratio on the basis of the calculated power of the first component and the calculated power of the second component.
