The FR28 from Micro Harmonics is a Waveguide Isolator that operates from 260 to 400 GHz. It can handle an input power of up to 0.3 W, provides an more than 17 dB of isolation and has an insertion loss of less than 5.6 dB. This isolator offers resistance against stray magnetic fields with an excellent performance in a compact size. The FR28 is available in a screw-mount module with anti-cocking WR-2.8 waveguide flange interface. It also integrates a diamond shaped heat-sink for better thermal management and dissipation.
