Abstract :
A new operation mode "Surfing mode" is proposed and verified experimentally in high-low-type GaAs IMPATTs. This mode is characterized by the concept that the avalanche charge pulse drifts synchronously with the movement of the front edge of the depletion layer at the higher velocity than the scattering-limited velocity. High- -low-type GaAs IMPATTs designed so as to operate effectively in the "Surfing mode" exhibited output powers 15 watts (ΔTj=210°C) at 6. 1 GHz 25 percent efficiencies.
