Abstract : Major effort during this past quarter has been to investigate a broadband traveling-wave limiter. A smooth passband of 1.4 GHz bandwidth has been realized and studies of limiter properties are continuing. Fabrication of a low-loss helix structure for the expander has begun. Preliminary investigations of ultrapure YIG samples have been made in an effort to understand the high level insertion loss observed in expander tests. (Author)
