LNF-LNC4_8E is an ultra-low noise cryogenic amplifier using LNF’s proprietary InP HEMT technology. The LNA is packaged in a module using Corning Gilbert GPPO coaxial connectors and a 5-pin strip DC connector. The lightweight gold plated aluminum body measures 27.34x21x4.3 mm. The LNA is stackable with a 140 mil pitch, suitable for Corning Gilbert GPPO multi-position 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.
