Summary: | A shared transmission and reception apparatus (OF-TRX) comprises a transmission and reception processing unit for mobile communication system B (TRX-B) which performs a frequency conversion process to a baseband signal for mobile communication system B outputted from a signal conversion unit (E/O), a power level adjusting unit (VA) which adjusts a power level of a wireless frequency signal for mobile communication system A inputted from a transmission and reception processing unit for mobile communication system A (TRX-A), a combining unit (COM) which combines the wireless frequency signal for mobile communication system A outputted from the power level adjusting unit (VA) and a wireless frequency signal for mobile communication system B outputted from the transmission and reception processing unit for mobile communication system B (TRX-B) and generates a transmission wireless frequency signal, and a common amplifier unit (PA) which amplifies the power level of the transmission wireless frequency signal outputted from the combining unit (COM) with a predetermined amplification factor and outputs it. |
