The CITCRYO1-12D is a cryogenic, low noise amplifier suitable for Radio Astronomy and Quantum applications. The amplifier covers the band from 1 to 12 GHz and is useable to 14 GHz. The amplifier has a typical noise temperature of 4 K with a gain of 36 dB. The standard configuration comes with SMA female connectors. The amplifier is also available in our NEW miniature “Drop-In” version which is 10 mm X 10 mm. CMT has also introduced a dual amplifier configuration.
