The CIT4-16 from Cosmic Microwave Technology is a Cryogenic Low Noise Amplifier that operates from 4 to 16 GHz. It provides 38 dB of gain with a noise figure of less than 1.7 dB (at room temperature) and has a noise temperature of less than 9 K (at 12 K). This amplifier requires one drain voltage from 0.6 V to 1.5 V and one gate voltage from -3 V to +1 V (requires a more negative gate supply voltage, typically -1.5 V, at room temperature). It is available in a module that measures 22.00 x 21.50 x 8.90 mm with SMA connectors. The amplifier is suitable for use in radio astronomy arrays, satellite and space communication applications.
