This ovenized voltage controlled SAW oscillator (VCSO) is extremely effective and reliable in applications involving use of analog signal processing, such as radar, communications, and electronic warfare (EW). Addition of a micro-oven to the design yields superior temperature stability (just +/- 10ppm over temperature range -40C to 85C). Specific emphasis on low phase noise, from the start of the design process, has led to a SAW oscillator of superior performance and quality.
