Low Noise Factory (LNF) has introduced a cryogenic low noise amplifier (LNA) that exhibits ultra-low noise over the operating frequency range from 1.2 to 3.5 GHz. The LNF-LNC1.2_3.5A is built using LNF’s proprietary InP HEMT technology and has an MMIC design that ensures excellent unit-to-unit variation. It provides a gain of 31 dB with a noise figure of 0.02 dB and has a noise temperature of 1.3 K.
This lightweight LNA does not have a hermetic sealing and therefore, requires operation in a vacuum environment when the temperature reaches below the dewpoint. It requires a DC supply of 1 V and consumes 20 mA of current. This cryogenic amplifier is available in a gold-plated Aluminum module that measures 19.4 x 17.6 x 7.8 mm and has standard SMA (female) connectors for RF ports and a 9-pin Nano-D (female) connector for DC power. The LNA has been tested at 296 K and 5 K. Click here to learn more about this new cryogenic ultra-low noise amplifier from LNF.
