Advanced Concepts of Microwave Generation and Control in Solids.
Abstract
The report deals with the progress made during the third quarterly period of a solid state microwave oscillator and amplifier research and development program. Discussed first is the progress on Gunn effect research. Work on the following specific topics is reviewed: high efficiency studies of LSA oscillators; some harmonic properties of an LSA oscillator; LSA circuit studies; control of silicon contamination in GaAs; a varactor tuned Gunn oscillator; and a Gunn effect amplifier. The progress made on a parallel program on avalanche and transit time diode devices is also described. The following specific topics are reviewed: experiments concerning harmonic generation; higher average power TRAPATT considerations; a new low noise Pt-n-p+ silicon Ku-band diode; a new program on an IMPATT amplifier for FM signals; harmonic generation and frequency mixing; integrated IMPATT and TRAPATT oscillators; high-frequency high-efficiency avalanche oscillations; and measurements of IMPATT diode parameters at microwave frequencies. Finally, the progress made on the studies of solid state materials for microwave devices are reported. The topics include: ion implantation and diffusion; vacuum expitaxial growth in silicon; and ionization rates in gallium arsenide. (Author)
