Abstract:
The present invention relates to a Doherty power amplifier in which a new operation mode for accomplishing high efficiency at a lower output power level is added to operation of a conventional Doherty power amplifier, thereby achieving high efficiency at various output power levels of the power amplifier. The multi-mode Doherty power amplifier to which a second power mode is added may be reduced in size so as to be integrated into a chip.
