Abstract :
New TRAPATT devices and circuits have been evolved for miniature solid-state transmitter applications. The devices, which are made by a low cost, high yield silicon planar technology process, are extremely rugged and generate high powers and efficiencies reproducibly. Peak output powers of 340 W have been achieved in conjunction with a DC to RF conversion efficiency of 35% from single diodes. At a 2% duty cycle the mean output power obtained with a 100 ns pulse length is 5.3 W at an efficiency of 32% at about 2.5 GHz.
