Design of Wideband Doherty Power Amplifier Using Inverse Continuous Class-F Mode
IEEE Transactions on Circuits and Systems - II - Express BriefsThis brief presents the theory and design method of a wideband Doherty power amplifier (DPA) using inverse continuous class-F mode (ICFM). It is illustrated that continuous class-F−1 mode impedance condition can be achieved for Doherty operation using a ...
