LNF-ISC2.8_4.3A and LNF-CIC2.8_4.3A are ultra-low insertion loss cryogenic isolators and circulators operating in the 2.8-4.3 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 43.94×43.18×12.7 mm excluding the connectors.
