The TTI-CLNA-C-0506 from TTI is a Low Noise Amplifier (LNA) that operates in the C-band from 5.7 to 6.3 GHz. It provides a gain of 40 dB (with a flatness of 0.5 dB peak-to-peak) and a noise temperature of less than 2.5 K. This cryogenic amplifier is manufactured using InP technology and is designed to operate at extremely low temperatures (4 to 15 K) with a low power consumption of 8 mW. This cryogenic LNA is available in a module that measures 39.3 x 26.0 x 9.0 mm and has SMA male/female connectors. It is ideal for radio astronomy, space communications, and quantum applications.
