LNF-XXXXXXC4_8A is an ultra-low insertion loss cryogenic triple 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 packed in a slim coaxial module using industry standard SMA connectors. The module measures 67.1*24.6*10.2 mm excluding the connectors.
