WR-51 Junction Isolator

18 to 21 GHz, 18 dB Isolation, WR-51 Waveguide
SNW-1832130418-51-I1 is a WR-51 waveguide junction isolator that covers the frequency range of 18 to 21 GHz. Compared with a Faraday isolator, the waveguide junction isolator offers a lower insertion loss of 0.4 dB maximum and a much shorter insertion length for system integration. As a tradeoff, the waveguide junction isolator only offers a minimum isolation of 18 dB. The input and output ports are WR-51 waveguides with UG-419/U flanges.
