CITCRYO4-12B
Cryogenic HEMT Low Noise Amplifier
Description
The CITCRYO4-12B is a cryogenic, low noise amplifier suitable for Radio Astronomy and Quantum applications. The amplifier covers the band from 4 to 12 GHz and is useable to 14 GHz. The amplifier has a typical noise temperature of 3.5 K with a gain of 35 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, and a chassis that incorporated shielded SMA connectors for ALL DC connections, amplifier supply and input DC Bias tees.
