LNF-LNC45_77WA
Cryogenic Low-Noise Amplifiers by Low Noise Factory (SE)
Overview
LNF-LNC45_77WA is an ultra-low noise cryogenic amplifier that employs Low Noise Factory’s proprietary InP HEMT MMIC technology, designed to deliver superior low-noise performance with consistency across units. It is housed in a gold-plated aluminum waveguide package using the WR15 standard for RF connections (UG387/U flange) and a Nano-D connector for DC input. The amplifier is optimized for operation in vacuum environments when cooled below the dewpoint and is tested at both room temperature (296 K) and cryogenic temperature (5 K). The design emphasizes exceptionally low noise figures and stable gain, making it suitable for advanced cryogenic microwave applications.
