Wiring and biasing of LNF’s cryogenic LNAs

When procuring cryogenic LNAs from LNF, our customers have the option to buy accessories to help with the proper wiring and biasing of them. Since a cryogenic LNA is located inside the end-user’s cryo cooler, LNF is unable to provide a standard solution for the wiring. Generally speaking, cryo coolers have different hermetic feedthroughs and the length of the wires inside and outside them differ in length. The allowed heat load from the wiring varies from case to case. LNF offers cables and accessories to make this wiring as easy as possible.
