29

Model OIS-290310-03-20-28 is a Ka band waveguide junction isolatorthat covers the frequency range of 29 to31 GHz. 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 atrade off, the waveguide junction isolator only offers a typical isolation of20dB. The input and output ports are WR-28 waveguides with UG-599/U flanges.
