LNF-CIC0.9_1.1A is ultra-low insertion loss cryogenic circulators operating in the 0.9-1.1 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 circulator is packaged in a slim coaxial module using industry standard SMA connectors. The module measures 31.5×30.86×12.7 mm excluding the connectors.
