Abstract :
The efficiency of a transferred electron device oscillator is calculated and optimized while fundamental and harmonic voltages of arbitrary magnitude and phase are applied to the device. Although lossy harmonic terminations are allowed in the optimization, most efficient operation requires reactive terminations. Proper termnations at the second and third harmonics double efficiency. The program shows a slight improvement in efficiency when the fourth or fifth voltage harmonics were added.
