Thermal processes effecting upon waveform shaping in autodyne gunn diode oscillators

The main factor influencing on system readiness time after power applying is the oscillator temperature variation due to self-heating of the oscillator diode. It is known that oscillator heating at its start leads to active and reactive conductance variation of the diode owing to which the amplitude and frequency variations occur as well as the respective differential parameters of diode about the steady-state. These variations influence upon the auto-detection and autodyne amplification factors as well as on the autodyne frequency deviation and the energy potential. Since it is impossible to eliminate completely this phenomenon, we must take it into account at development of each SRR.
