发明名称 Radio device
摘要 A radio device in which a variation in the match condition of the antenna, occurring due to a change in the antenna itself or the surrounding environment, is detected based on the amount of reflection or a variation in the current consumption of the power amplifier. If such a variation is detected, the match condition of the antenna itself is changed by connecting the antenna to a terminator or to a matching element, or by using a spare antenna whose match condition has not been varied. Thus, it is possible to prevent the power amplifier from being broken.
