ABSTRACT:
A flux drive gyromagnetic system such as a gyromagnetic waveguide phase shifter is temperature compensated by measuring the flux change in the gyromagnetic material during a reverse in saturation magnetization, comparing that change to the change under reference conditions and modifying the drive used to set the gyromagnetic material to a non-saturated condition in accordance with the results of the comparison.
