Abstract
A shared AMP includes: a transmission/reception processor section (TRX-B) for a second mobile communication system configured to perform frequency conversion processing on an inputted transmission baseband signal for a mobile communication system B, and to output a transmission radio frequency signal for the second mobile communication system; a power level adjuster section (VA) configured to adjust a power level of an inputted transmission radio frequency signal for a first mobile communication system; a combiner section (COM) configured to generate a transmission radio frequency signal, by combining the transmission radio frequency signal for the first mobile communication system outputted from the power level adjuster section (VA) and the transmission radio frequency signal for the second mobile communication system outputted from the transmission/reception processor section (TRX-B) for the second mobile communication system; and a common amplifier section (PA) configured to amplify a power level of the transmission radio frequency signal outputted from the combiner section (COM) at a predetermined amplification rate, and to output the resultant signal.
