A multi-IMPATT injection-locked oscillator at 35 GHz

A 35-GHz solid-state injection-locked oscillator giving 38 W peak power with 30% duty cycle is described. The power source utilizes a total of ten GaAs IMPATT (impact avalanche and transit time) diodes grouped in two stages. The performance of the source as well as the systematic design and measurement procedures used to develop the multidiode cavities used are discussed.<
