Radio transmitter and method of controlling transmission by radio transmitter

A radio transmitter comprising:

• a transmission power control means for controlling a gain thereof according to a control signal applied thereto and for amplifying a radio frequency (RF) signal input thereto to generate an RF output signal having a predetermined power;
• a power monitoring means for monitoring the RF output signal so as to obtain an average power level of the RF output signal;
• an error calculating means for calculating an error level from the difference between the average power level and a reference power level which corresponds to the predetermined power;
• and
• a control signal generating means for multiplying the error level by a correction coefficient so as to obtain a control signal correction value for correcting the value of the control signal, and adjusting the value of the control signal to be delivered to said transmission power control means on the basis of the control signal correction value and a reference control value that is predetermined so as to generate an RF output signal having the predetermined power.
