PROBLEM TO BE SOLVED: To solve the following problems:when an operator adjusts stipulated power for frequencies to be used by a radio device, which is not known by a manufacturer and decided by the user after manufacture, the power is adjusted for all the frequencies used, meanwhile, in a radio device whose stipulated power is adjusted for each frequency band by the manufacturer, there is no need for the operator to adjust the power, while there remains variation of a power amplifiers and the stipulated power is varied in transmission output. SOLUTION: The stipulated power is automatically adjusted for the use frequency, the variation due to the frequency characteristics of the power amplifier is reduced, and the transmission output at the stipulated power can be achieved. Also, the power can be automatically adjusted to stipulated output with less deviation, without using a measuring device such as a wattmeter. COPYRIGHT: (C)2011,JPO&INPIT
