Abstract
A broadband Doherty power amplifier is provided, which includes a power divider, a carrier power amplifier circuit, a peak power amplifier circuit, and a load modulation network. The carrier power amplifier circuit includes a carrier input matching circuit, a carrier power amplifier, and a carrier output matching circuit. The peak power amplifier circuit includes a peak input matching circuit, a peak power amplifier and a peak output matching circuit. A resistance value of a system load is Z. An output impedance of the carrier output matching circuit is Zand meets Z=Z(n+1). An output impedance of the peak output matching circuit is Zand meets Z=Z(n+1)/n. The load modulation network is configured to set an impedance of a combination point to be Z, whose resistance value is Z. A method of implementing a broadband Doherty power amplifier is further provided.
