LNF-ISC2_2.8A and LNF-CIC2_2.8A are ultra-low insertion loss cryogenic isolators and circulators operating in the 2 – 2.8 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 22.86×22.56×12.7 mm for the circulator and 22.86×35.56×12.7 mm for the isolator excluding the connectors.
