Project Description

Low-Loss Ferrite Components for NASA Missions, Phase II
The goal of this research is to develop high-frequency Faraday rotation isolators that exhibit significantly reduced loss, higher power handling and improved bandwidth over commercially available products. The bandwidth limitations of high-frequency circulators will be explored. It was demonstrated in the Phase I work that the bandwidth of these components can be substantially increased through impedance matching techniques. At the end of the Phase II program, Micro Harmonics will have developed a full line of isolators operating in bands from WR-12 through WR-3 and circulators working in bands from WR-15 through WR-5. In the phase I work our models were proven to be accurate. The approach is fundamentally sound, but there are significant technical challenges. These components will find immediate use in a broad range of systems used by NASA as well as the commercial sector. More »
