摘要： Disclosed is a 3-way Doherty power amplifier using a driving amplifier in which driving amplifiers are connected to the front stages of a carrier amplifier and a peaking amplifier, respectively, so as to obtain a high gain and a high efficiency. To this end, the Doherty power amplifier includes: a hybrid power distributor for distributing an input signal into first and second path units; and a driving amplifier for receiving a signal outputted from the hybrid power distributor and controlling the driving of a carrier amplifier, a first peaking amplifier, and a second peaking amplifier, wherein: the carrier amplifier, the first peaking amplifier, and the second peaking amplifier are connected to a rear stage of the driving amplifier, respectively; the first path unit generates a high efficiency at a low input power; and the second path unit maintains a high efficiency and gain in a high output range.
