ABSTRACT:
A frequency locked loop having a surface acoustic wave time delay device disposed on the same substrate, or a substrate on the same material, as a surface acoustic wave device being compensated. As temperature causes changes in the surface acoustic wave device, changes in the time delay of the surface acoustic wave time delay device will also occur. These changes in the time delay are used by the frequency locked loop to adjust the frequency of an incoming signal of the frequency locked loop and to provide an adjusted input signal frequency to the surface acoustic wave device. This adjusted input compensates for the change in the output caused by the temperature change.
