Abstract :
Theoretical considerations and experimental studies of a microwave harmonic generator using the nonlinearity of negative resistance in n type GaAs for a small-signal excitation are performed to develop solid-state millimetre-wave devices. Experimental results using a Gunn diode show the very high conversion efficiency and the possibility of millimetre-wave generation.
