Abstract :
In this paper, high efficiency power amplifier for Beidou satellite navigation system is presented. The continuous Class-F PAs will be promising candidate for performances of broadband efficiency and power. Meanwhile, stability networks are also integrated into the layout to prevent low-frequency oscillations. Cree GaN HEMT CGH40010F is used in design of proposal PA. Simulation results show drain efficiency from 63% to 69% and output powers from 11.3-12.3 W over frequency of 1.1 to 1.7 GHz.
