Design of Broadband Low Voltage Class-F Power Amplifier Using Radial-Stub

This paper presents a design of broadband low voltage Class-F Power amplifier (PA), using a radial-stub. To have control harmonics and output matching, a harmonic control network with a radial-stub is designed. Using a power transistor pHEMT ATF-34143 with 1.8 V supply voltage, greater than 42% power added efficiency (PAE) has been simulated over a 1.7 to 2.8 GHz bandwidth. The maximum PAE value of the proposed broadband Class-F PA is 85% under 20dBm output power and 13 dBm input power at 2.7 GHz.
