• RF bandwidth: 4-8 GHz
  • Insertion loss: 0.17 dB typical
  • Isolation: 22 dB typical
  • Port match: 22 dB typical
  • RF-connectors: SMA


LNF-ISC4_8A and LNF-CIC4_8A are ultra-low insertion loss cryogenic isolators and circulators operating in the 4-8 GHz frequency range. They have been designed from ground up to meet the strict requirements of ultra-low temperature physics research. The gold plated OFHC copper body ensures minimum loss and that this loss reaches the lowest possible temperature to minimize thermal noise. The isolator/circulator is packed in a slim coaxial module using industry standard SMA connectors. The module measures 22.3*24.6*10.2 mm excluding the connectors.
