A new concept for high-efficiency operation of high-low-type GaAs IMPATT diodes
Abstract
A new operation mode, the 'surfing mode,' is proposed as an explanation for the high-efficiency operation of high-low-type GaAs IMPATT diodes. 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 a velocity higher than the saturation velocity. The design chart of high-low-type GaAs IMPATT diodes is determined on the basis of the concept of the 'surfing mode.' The high-low-type GaAs IMPATT diodes designed using this chart exhibited output powers of 15.3 W at 6.1 GHz with 25-percent efficiency.
