LNF-LNC4_8SF is an ultra-low noise cryogenic amplifier using LNF’s proprietary InP HEMT technology. The LNA is packaged in a module using Corning Gilbert G3PO coaxial connectors and a 5-pin strip DC connector. The lightweight gold plated aluminum body measures 18.0×15.0x3.556 mm. The LNA is stackable with a 140 mil pitch, suitable for Corning Gilbert G3PO multiposition blocks. The LNA is not hermetic and must be operated in a vacuum environment when below the dewpoint. All amplifiers are tested at 296 and 5 K and delivered with a test report.
