Abstract :
The experimental research of characteristics of the microwave oscillator based on the structure of static inductance transistor has been carried out and the model of its static and dynamic current-voltage characteristics has been improved. The results of the experimental research show that oscillating frequency changes from 770 to 900MHz, amplitude of generate oscillations changes from 5 to 22 V, average power of oscillations is 96mW, coefficient of efficiency is 80-85% when supply voltage variation is from 9 to 30 V. Calculation of characteristics by means of the simplified charge model of the structure of static inductance transistor gives quite accurate description of characteristics of the active element of the oscillator.
