Abstract
The device–circuit interaction is considered for a Trapatt diode when the induced avalanche current is so high that it is the circuit which forces the voltage to collapse aeross the diode rather than the distribution of the charge in the diode. This mode of operation gives a circuit dominated oscillator and the ideal theoretical results appear to account for experimental observations on typical L band Trapatt oscillators. The effects of serics loss are considered and it is shown that RC/τ must scale if the efficiency is to be preserved with increasing frequency. Values of RC/τ as low as 0.025 are considered necessary for efficiencies over 35% if reasonablo depletion lengths are to be maintained. Implications for scaling are considered.Keywords
