click here to view PDF: Rectangular Waveguide Isolators
Space Machine & Engineering offers a standard product line of rectangular waveguide ferrite Isolators covering waveguide sizes WR62, WR75, WR90, WR112, WR137, WR159, WR187, WR229, and 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.
