Abstract
The present invention provides a transmitting apparatus equipped with a modulator, a frequency converter that up-converts a modulated signal (or digital IF signal) of a baseband, and an amplifier that amplifies a transmit signal lying in a radio frequency band to a desired signal level. In the transmitting apparatus, a controller including a level determinater and a bias setter is provided with a limiter setter. The level determinater and bias setter of the controller setter perform dynamic bias control of the amplifier. Further, the limiter setter changes the setting of a threshold value of the limiter according to an average level of an input signal.
