High Power C Band Phase Shifters

The report outlines all tasks performed under this program and includes techniques performed in developing high power phase shifters and a description of the hardware delivered with test results. Structural studies have been carried out to assure compatability of designs with phased array requirements. Cross sections have been reduced to a minimum by careful location of cooling structures. Remote driving techniques were developed with emphasis on switching efficiency. A scheme of triggering a single bit phase shifter is outlined in detail. Studies of flux drive led to a better understanding of practical and theoretical limitations, these limitations being discussed in detail. A direct comparison of single and multibit phase shifters is given with emphasis on microwave performance and relative cost.
