| High frequency and microwave oscillators are used in many communications systems. Their design is most often based on feedback amplifier techniques which does not lend itself to efficient integrated circuit fabrication. This thesis explores the use of astable multivibrators and other relaxation oscillators, built as GaAs Monolithic Microwave Integrated Circuit components, as microwave signal sources. Several oscillator topologies are explored and compared against conventional oscillators for both fixed frequency and voltage controlled oscillator applications. |
