  • Temperature compensation circuitry
    Patent number: 4639697
    Abstract: A surface acoustic wave (SAW) device provides a phase shift and a first predetermined phase shift variation as a function of temperature. A passive network including a passive, reactive component is thermally and electrically coupled to the SAW device. An electrical characteristic of the component has a predetermined variation as a function of the temperature of the reactive component which provides the network with a second, predetermined phase variation as a function of temperature to compensate for the first predetermined phase variation as a function of temperature provided from the surface acoustic wave device. With this arrangement, the phase shift provided from the surface acoustic wave device is substantially invariant with temperature.
