| 内容記述 | Wide application has been predicted for SAW oscillators because of their simple fabrication capability and direct oscillation in the UHF band. However, an oscillator stable over a wide temperature range has been difficult to nanufacture because of the lack of substrates with low-temperature coefficient over a wide temperature range. To overcome this difficulty, several temperature compensation methods have been investigated, including the usage of composite materials, parallel and series connected delay lines, and ovening. This paper introduces a novel compensation technique that does not require external electrical components and complex SAW transducer modification. It is shown that a significant improvement in temperature stability can be achieved by connecting multiple SAW renonators with a simply structured IDT, providing these resonators have different temperature characteristics. Since these resonators may be fabricated on a single substrate, the oscillator can be massproduced using photolithography. Many implementations are possible such as using an arbitrary number of resonators, or combining second and higher order temperature coefficient substrates. This paper illustrates the principle by considering the advantages of using two resonators with second-order temperature coefficients. By using resonators on 35 \deg\ and 46 \deg\ rotated Y-cut quartz substrates, a temperature stable oscillator has been obtained which has less than 2 x 10^-6 frequency variation over a 60C temperature range. | |||||
