The present invention, as a power amplifier for supplying a high-frequency signal, and an antenna for transmitting the high-frequency signal transmission line for transmitting the high frequency signal to the antenna from the power amplifier, a radio frequency, including an impedance matching circuit coupled to the transmission line a signal transmitter. In addition, the high frequency signal transmitter includes mismatch detector. Mismatch detector is divided into a Smith chart on the basis of the contour adjacent channel power ratio (ACPR) plotted on the Smith chart at a point connected to the impedance matching circuit transmission line into two regions with a relatively linearity is poor region and a relatively linear and good area specified, and the radio frequency signal was measured, and the reflection coefficient for the reflection coefficient at the phase and the size surface of the transmitter that can vary over time and determine whether or not the relative linearity is poor region or position in a good area the relatively linear, that determination on the basis of the result, thereby improving the linearity of the transmitter high-frequency signal.
