Abstract : The behavior of several different Gunn oscillators operating into a resistive load is experimentally investigated. The effects of applied bias, load resistance, and temperature on oscillation frequency, power, and efficiency are presented. It is seen that at microwave frequencies circuit resonances influence diode behavior and that complete knowledge of the microwave circuit is required. It is then demonstrated that under certain circumstances, such as for the diodes and circuit employed here, the domain capacitance plays a major role in determining frequency behavior and can lead to wide tuning ranges and mode switching determined by the applied voltage or temperature. Applications of this effect and follow-on work are suggested. (Author)
