Network which connects the proposed Class-F power amplifier (PA) load and the drain connecting must exhibit multifunctional properties in order to get best performance from an active device. In this paper, a Class-F PA is introduced for which a multifunctional WHIP network is implemented to achieve maximum power efficiency using the Cree Wolfspeed CGH40010F GaN HEMT. The WHIP network is utilised to terminate the drain of the GaN HEMT alongside the necessary load impedances at the 1st, 2nd, and 3rd harmonic frequencies. The working of the PA is verified using ADS simulations and validated by measurements of a constructed prototype. The PA delivers a maximum power efficiency of 82% and gets the power output which is maximum of 40.06 dBm at 2.1 GHz.

摘要

Network which connects the proposed Class-F power amplifier (PA) load and the drain connecting must exhibit multifunctional properties in order to get best performance from an active device. In this paper, a Class-F PA is introduced for which a multifunctional WHIP network is implemented to achieve maximum power efficiency using the Cree Wolfspeed CGH40010F GaN HEMT. The WHIP network is utilised to terminate the drain of the GaN HEMT alongside the necessary load impedances at the 1st, 2nd, and 3rd harmonic frequencies. The working of the PA is verified using ADS simulations and validated by measurements of a constructed prototype. The PA delivers a maximum power efficiency of 82% and gets the power output which is maximum of 40.06 dBm at 2.1 GHz.
