MetadataShow full item record
Then: are principal advances in the field of application of surface acoustic wave (SAW) delay lines and resonators in stable microwave frequency sources in the frequency range from 100 MHz to 1 GHz and above Advances, applications and fundamental design will be described. The center frequencies of the realized oscillators are near 70 MHz and 200 MHz. Requirements for the amplifier are presented Results from frequency variation and modulation are demonstrated. Miniature SAW oscillators have been designed and fabricated based upon a combination of hybrid electronic circuitry and SAW delay line. The package for the oscillator is a PDL 24 with a volume of 28 X 34 X 5 mm³ This results in a rugged system Measurements of short and medium term stability of the oscillators will be described.
