Japanese Patent JP4937031

B2

A shared transmission/reception apparatus (OF-TRX) includes: a transmission/reception processor section (TRX-B) for a mobile communication system B configured to perform frequency conversion processing on a transmission baseband signal for the mobile communication system B outputted from a signal converter section (E/O), and to output a transmission radio frequency signal for the mobile communication system B; a power level adjuster section (VA) configured to adjust a power level of a transmission radio frequency signal for a mobile communication system A inputted from a transmission/reception processor section (TRX-A) for the mobile communication system A; a combiner section (COM) configured to generate a transmission radio frequency signal by combining the transmission radio frequency signal for the mobile communication system A outputted from the power level adjuster section (VA) and the transmission radio frequency signal for the mobile communication system B outputted from the transmission/reception processor section (TRX-B) for the mobile communication system B; 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.
