The 9104-CRYO from Spectrum Control are Cryogenic Fixed Attenuators that operate from DC to 40 GHz. They are available in attenuation values of 0, 3, 6, 10, 20, & 30 dB and offer stable attenuation over temperature. The attenuators can handle an average input power of 2 W and have a VSWR of less than 1.40:1. They use APITech’s in-house resistor fabrication process and have been tested to a temperature of 4 mK. These RoHS-compliant attenuators have low thermal noise characteristics, minimal self-heating with optimized non-magnetic material selection. They are available as connectorized modules with 2.92 mm Male/Female connectors.
