Abstract
Discrete data of a base-band signal obtained by a control unit is multiplied by data equivalent to a time constant of a wave detector unit, thus enabling the deterioration in a detection voltage generated during detection of a modulation wave having a marked variation in amplitudes such as CDMA. It is possible to obtain a stable power outputted by an RF unit. Accordingly, the stable automatic gain control can be performed in consideration of the variation in the detection voltages due to the type of signals inputted to the wave detector unit, irrespective of the type of inputted signals.
