Abstract :
A new two-terminal millimetre wave transit-time device is presented that can be used for power generation. Theoretical calculations predict good noise properties. DC measurements are in agreement with a theoretical model of current transport across the employed GaAs/GaAlAs heterojunction. A first realisation of the structure leads to several milliwatts of power output at 60 GHz under pulsed conditions
