4-8 GHz Single Junction Isolator/Circulator

RF bandwidth 4-8 GHz
Insertion loss 0.17 dB typical
Isolation 22 dB typical

RF connectors Female 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 packaged in a slim coaxial module using industry standard SMA connectors. The module measures 22.3×24.6×10.2 mm excluding the connectors.
