PROBLEM TO BE SOLVED: To provide a radio device capable of downsizing, light-weighting, and cost saving.SOLUTION: A radio device includes: an amplification part 20 for power amplification of a transmission signal; a transmission filter 32 to which output of the amplification part 20 is inputted; and a control part to which output of the amplification part 20 is inputted as a feedback signal, for performing distortion compensation control which adjusts a phase and amplitude of a transmission signal, to be inputted to the amplification part 20 so that a spectrum of the feedback signal and a spectrum of the transmission signal matches. The amplification part 20 includes a first path 6a having an inter-stage filter 7 and a second path 6b configured to yield a transmission delay same as the first path 6a, selectively switches the paths 6a and 6b, and transmits a transmission signal through the selected path. The control part makes the amplification part 20 alternately select the first path 6a and the second path 6b, halts the distortion compensation control during a first period in which the first path 6a is selected, and performs the distortion compensation control during a second period in which the second path is selected. |
