Abstract :
An analytic approach to the design of high efficiency tuned power oscillator is presented. By employing large-signal S-parameters, theoretical conditions for optimum operation of the oscillator have been formulated and discussed. Loss due to non-zero switching time, saturation resistance etc. of the transistor employed is accounted for. Various oscillators at 900 MHz were designed using the derived theory. Experimental results showed that the measured data are in good agreement with the predicted data
