LNF-XXXX4_8B is an ultra-low insertion loss cryogenic 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 32mm x 21.46mm x 10.16mm excluding the connectors.
