LNF-LNC23_42WB 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 waveguide module using industry standard WR28 for the RF ports and Nano-D connectors to provide the DC. The lightweight gold plated aluminum body measures 22.70×29.91×19.20 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.
