Abstract
A Doherty power amplifier includes a main power amplification circuit, an auxiliary power amplification circuit, a connection circuit, and an impedance conversion circuit. An output end of the main power amplification circuit and an output end of the auxiliary power amplification circuit are connected to two ends of the connection circuit separately by using bonding wires. The output end of the auxiliary power amplification circuit is further connected to one end of the impedance conversion circuit by using a bonding wire, and the other end of the impedance conversion circuit is connected to an output load.
