The CITCRYO1-12D is a cryogenic, low noise, broadband amplifier. In its standard configuration it comes with female SMA connectors on the RF-input and output and a 4-pin 2 mm pitch header for the DC. The amplifier requires three separate DC-voltages. For more information and complete specs, please download the pdf data sheet on the left.
