Abstract
In the radio equipment in which necessary absolute precision of the transmit power can be assured while keeping the power variable amount precision in transmit power adjustment and the transmit power control of wide dynamic range and high linearity also is requested. The transmit power controlling method in the radio equipment, and the recording medium, when the transmit power is adjusted by detecting the error based on difference between the detected value which is obtained by detecting the transmit signal of the radio equipment and the detected value of the transmit signal when it is transmitted by the designated transmit power to be transmitted, then calculating the correction value by multiplying this error by the predetermined gain, then generating the control amount based on the correction value, and then re-setting the gain in transmit power amplification based on the control amount at a predetermined timing, the predetermined gain can be set such that an amount of change in the transmit power to be adjusted based on the control amount can be suppressed in the allowable range requested for an amount of change in the transmit power to be adjusted based on the reference value of the transmit power control, which is generated based on the designated transmit power.
