Multi-domain Gunn diodes with multiple hot electron launchers: a new approach to MM wave GaAs Gunn oscillator optimization

The optimization of millimeter wave Gunn oscillators comprises two avenues, namely the use of heterojunctions for hot electron injection and multidomain operation Gunn diodes. A combination of these two techniques is proposed resulting in multiple hot electron launchers spaced throughout the diode. The results presented here suggest that this configuration proves to be a very promising option which warrants further investigation.
