Abstract:
A transmission power control apparatus being able to control a power level of the transmission signal comprising:variable gain amplifying means for amplifying an input signal at a specified gain;fixed gain amplifying means connected in series to the variable gain amplifying means, for amplifying, at a fixed gain, the input signal amplified by the variable gain amplifying means, the variable gain amplifying means and the fixed gain amplifying means being for adjusting the power level of the transmission signal;bypassing means for forming a bypass route for transmitting the transmission signal so as to bypass the fixed gain amplifying means; andgain control means for specifying the gain of the variable gain amplifying means so that the transmission power has a necessary value, and for determining whether the bypassing means is formed the bypass route or not by comparing the necessary value of the transmission power with a predetermined first threshold value and a predetermined second threshold value which is higher than the first threshold value.
