Abstract
A compact, liquid cooled, ferrite phase shifter is capable of handling high power microwave signals without thermally stressing the ferrite core. The ferrite core is mounted on spacers inside of a hermetically sealed wave guide filled with a thermally conducting fluid. Heat transfer from the core to the housing is symmetrical thereby eliminating or minimizing thermal bending stresses on the phase shifter. Heat from the core is also coupled through the fluid to the phase shifter window for deicing the window.
