U-Band Junction Isolator

39 to 44 GHz, 18 dB Isolation, WR-19 Waveguide
SNW-3934430518-19-I1 is a Q band waveguide junction isolator that covers the frequency range of 39.0 to 44.0 GHz. Compared with a Faraday isolator, the waveguide junction isolator offers a lower insertion loss of 0.5 dB nominal and a much shorter insertion length for system integration. As a tradeoff, the waveguide junction isolator only offers an isolation of 18 dB typical. The input and output ports are WR-19 waveguides with UG-383/U-M anti-cocking flanges. Various configurations and frequency ranges are offered under different model numbers.
