In this paper, a Load-pull technique to design a class-F power amplifier with multi-coupler network is presented. The fundamental load impedance and matching networks are separately integrated for class-F RF power amplifier high efficiency operation. The output used a transmitting type active integrated antenna. A Cree GaN FET CGH40006F transistor device at 3.50 GHz operating frequency was used in the design. The performance of the network has improved by 79.4% power added efficiency at 30.1dBm output power. This technique has been considered a useful for improving performance in mobile communication applications.
