Abstract:
1. An apparatus for transmitting an RF (Radio Frequency) signal in a mobile communication terminal, comprising: a step-up converter for converting a signal to be transmitted into a signal of a transmission band; a reverse variable attenuator for performing high attenuation or low attenuation about an output signal of the step-up converter according to an attenuation control value; a transmission power processor for raising power of an output signal of the reverse variable attenuator to transmission power; and a controller for generating the attenuation control value used for performing said high attenuation with respect to a predetermined attenuation threshold value if the signal to be transmitted requires a low output power level with respect to a predetermined power threshold, whereas performing said low attenuation with respect to the predetermined attenuation threshold value if the signal to be transmitted requires a high output power level with respect to the predetermined power threshold value.
