Model OIS-340360-03-20-28 is a Ka band waveguide junction isolatorthat covers the frequency range of 34 to 36GHz. Compared with a Faradayisolator, the waveguide junction isolator offers a lower insertion loss of 0.3dB typical and a much shorter insertion length for system integration. As a trade off, the waveguide junction isolator only offers a typical isolation of 20dB. The input and output ports are WR-28 waveguides with UG-599/Uflanges.

Model OIS-42 is a K band,wave guide junction isolator that covers thefrequency range of 18 to 26.5 GHz. The full band isolator is designed andmanufactured to provide a low insertion loss of 0.3dB typical with good flatness.Compared to a Faraday isolator,it offers a much shorter insertion lengthfor systemintegration. The isolator also offers a moderate isolation of 20dB. Theinput and output ports are WR-42waveguides with UG-595/U flanges.
