Surface Acoustic Wave Microwave Oscillator and Frequency Synthesizer.
Abstract
The objective of the program is the development of Surface Acoustic Wave (SAW) oscillator and synthesizer technology. The two year effort is planned as follows: Task I - Development of SAW devices for oscillator applications at microwave (L-band) frequencies. Emphasis to be placed on achieving wideband tuning capabilities, improved oscillator stability performance and reduced power requirements. Task II - Investigate UHF surface acoustic wave devices which can best impact on synthesizer performance parameters such as: switching speed, minimum frequency step size, total achievable bandwidth, short, medium and long term stability as well as maximum suppression of spurious mode level. Concurrently promising new synthesizer designs will be studied on the basis of these designs to arrive at target specification in a package providing a significant reduction in size, weight and power consumption. Since Task I was completed prior to this reporting period, during the third six months of the program design of the synthesizer circuitry was largely completed. SAW delay line/filters to be used in both the injection locked SAW oscillators and in the SAW Filter Bank have been designed and are being fabricated. The design of the delay lines was based partially on an investigation of the injection locking properties of SAW oscillators. RF/LSI circuitry has been processed and is currently being tested.
