Abstract:

The design and applications of epitaxial yttrium iron garnet YIG magnetostatic wave devices will depend upon the variation of the device characteristics versus temperature. A theoretical expression of the delay line oscillator frequency temperature coefficient has been calculated for the three kinds of magnetostatic waves and a comparison between theoretical and experimental results has been done. Temperature stabilization of the frequency of a magnetostatic forward volume wave delay line oscillator has been obtained through the use of a permanent bias magnet made of magnetic materials with a suitable temperature coefficient. Its center frequency of 7.665 GHz is stable to within or - 1 MHz over the temperature range extending from 46 C to 111 C. Author
