In this paper, the propagation effect of power supply uncertainty on the output of class-F power amplifier has been estimated. Also, a 1.9 GHz, 10 watt class-F power amplifier was measured to verify the estimation and to find the optimal biasing point. By approxi-mating the propagation theory of uncertainties, the propagation effect of bias uncertainty was mathmatically calculated. As a result, the DC biases have propagated uncertainties of 15`70 mW. However, at the optimized bias point, the uncertainty in the output power could be dropped less than 15 mW while the output power has dropped by 0.37 dB.Key words: Uncertainty, Power Amplifier, Propagation of Uncertainty k lm 2013no 6pqp 5nrrslmt V[ %0 u vj.w 6pqp 5nr x=nZ(Department of Electronics Engineering, Hankuk University of Foreign Studies) *yS5nrz{|=nZ(Department of Computer Science and Engineering, Hyupsung University)Manuscript received November 15, 2013 ; Revised January 22, 2014 ; Accepted January 22, 2014.
