  • Wide band Doherty power amplifier
    Patent number: 11070173
    Abstract: A wideband power amplifier is presented. The wideband power amplifier configured to be coupled to a load having an impedance ZL, where the wideband power amplifier comprises: a quadrature coupler; a carrier amplifier coupled to the quadrature coupler; a peak amplifier coupled to the quadrature coupler; wherein the carrier amplifier saturates at an input power level lower than the input power level at which the peak amplifier saturates; wherein each of the carrier amplifier and the peak amplifier has a termination impedance of approximately Ropt, where Ropt is the optimum impedance at which the carrier amplifier and the peak amplifier will deliver rated max powers; a impedance transformer, coupled to the carrier amplifier having a characteristic impedance of 2*Ropt; an impedance transformer, coupled to the peak amplifier and the impedance transformer; wherein the impedance transformer is configured transform a load impedance ZL to 2*Ropt.
