Abstract :
Efficiency enhancement was experimentally demonstrated for a Ku-band extended interaction oscillator which features a five-gap interaction cavity with a coaxial section placed between the first and second gaps for ballistic bunching of electrons. Oscillation power of 2.2 kW at 30% electronic efficiency and 41% total efficiency with a depressed collector was achieved.
