ABSTRACT:
The invention provides a phase-shifting device for inclusion into a microwave transmission line to effect a predetermined, constant, broadband shift in phase of transmitted signals. The device comprises, in its preferred form, two Gallium Arsenide field effect transistors, connected in parallel, serially included in the line, and means for switching the transistors between alternate states to effect the phase shift.
