Highlights

Space Machine & Engineering offers a standard product line of rectangular waveguide ferrite Isolators covering waveguide sizes WR62 thru WR284. These Isolators are permanent magnet 3 port devices that use a Y-junction structure housed in standard rectangular waveguide with the addition of a matched termination. Greater isolation, better insertion loss and VSWR are achievable with reduced bandwidths. Please specify required bandwidth and pressurization requirements when ordering.
