2142-CRYO Fixed Attenuator by Spectrum Control
The 2142-CRYO from Spectrum Control are Bulkhead Cryogenic Attenuators that operate from DC to 18 GHz. They are available in attenuation values of 3, 6, 10, and 20 dB with an accuracy of ±0.5 dB. The attenuators use APITech’s in-house resistor fabrication process and have been tested to temperatures of 4 mK. They can handle up to 2 W of input power and peak power of 250 W at either port. The attenuators have low thermal noise characteristics, minimal self-heating with optimized non-magnetic material selections. These RoHS-compliant attenuators have SMA connectors.
