Abstract
An amplifying apparatus includes a splitting unit for splitting an input signal into a first split signal and a second split signal; phase-shifting unit for phase-shifting the first split signal and the second split signal, respectively; a first amplifying unit for amplifying a first phase-shifted signal and outputting the signal as a first output signal; a second amplifying unit for amplifying, in a substantially identical manner to the first amplifying unit, a second phase-shifted signal and outputting the signal as a second output signal; and a matching unit for matching the first output signal and the second output signal to a first transmission unit and a second transmission unit, respectively. The first transmission unit is for transmitting the first output signal from the matching unit to a load resistor, and the second transmission unit is for transmitting the second output signal from the matching unit to the load resistor.
