Cryogenic Isolators / Circulators

4-8 GHz Single Junction Isolator/Circulator

  • Frequency Range 4 – 8 GHz
  • Insertion Loss 0.17 dB typical
  • Isolation 22 dB typical
  • Port Match 22 dB typical
  • Body Gold-plated OFHC copper
  • RF Connectors Female SMA
  • Ultra-low insertion loss cryogenic isolator/circulator for 4–8 GHz. Designed from ground up for ultra-low temperature physics research, where every fraction of a kelvin of noise added by passive components counts
  • Gold-plated OFHC (oxygen-free high-conductivity) copper body ensures minimum insertion loss and guarantees that this loss thermalises to the lowest possible temperature, minimising added thermal noise at the LNA input
  • Available as either an isolator or a circulator in the same slim SMA coaxial module
