LNF-LNC0.3_14B is an ultra-low noise cryogenic amplifier using LNF’s proprietary InP HEMT technology. MMIC technology ensures excellent unit-to-unit variation. The LNA is packaged in a coaxial module using industry standard SMA connectors for the RF ports and Nano-D to provide the DC. The lightweight gold plated aluminum body measures 19.87×19.6×7.8 mm excluding the connectors. 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.
