Recent advances in digital latching ferrite devices

This paper is concerned with the design and development of several new types of non-reciprocal latching ferrite devices. These devices have been designed to exhibit improved electrical performance at reduced per unit cost. Some of the described devices include (1)a single toroiddigital waveguide phase shifter, (2) a second generation temperature compensated, high average power phase shifter, (3) a digital strip transmission line phase shifter, (4) a miniaturized slow wave phase shifter, and (5) a latching ferrite waveguide cutoff switch. In addition to describing the design and operating characteristics of these devices, the results of recent experiments with digital reciprocal phase shifters are presented.
