Abstract
A transmission apparatus with reduced current consumption for a mobile terminal is disclosed. The transmission apparatus includes an automatic gain control (AGC) amplifier for AGC-amplifying an input baseband signal; an attenuator for attenuating an output signal of the AGC amplifier; a multiplier for multiplying an output signal of the attenuator by a carrier frequency signal to convert the signal into a radio frequency (RF) signal; a first filter for filtering an output signal of the multiplier; a drive amplifier for amplifying an output signal of the first filter; a second filter for filtering an output signal of the drive amplifier; a power amplifier for amplifying an output signal of the second filter; and an antenna. When output power of the mobile terminal is lower than predetermined maximum output power of the AGC amplifier, the output signal of the AGC amplifier is transmitted through the multiplier, the first filter and the antenna.
