Insertion loss 0.2 dB typical
Isolation 42 dB typical
Port match 22 dB typical
RF connectors Female SMA

LNF-xxxxC4_8A is an ultra-low insertion loss cryogenic dual junction isolator/circulator operating in the 4‑8 GHz frequency range. It has 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 44.7×24.6×10.2 mm excluding the connectors.
