LNF-LNC23_42B 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 K (2.92mm) connectors for the RF ports and Nano-D to provide the DC. The lightweight gold plated aluminum module measures 17.80×15.15×6.80 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.
