The LNF-ISC2.8_4.3A from Low Noise Factory is a Cryogenic Single Junction Isolator that operates from 2.8 to 4.3 GHz. At 77K, it has an insertion loss of 0.2 dB and provides 20 dB of isolation. This isolator has an operating temperature range from 0.01 K to 100 K and has been designed 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. It is available in a module that measures 43.94 x 43.18 x 12.7 mm and has SMA-female connectors.
