LNF-LNC28_52WB 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 WR22 for the RF ports and Nano-D connectors to provide the DC. 

The lightweight gold plated aluminum body measures 28.0×19.52×19.2 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.
