QMC-CRYOATTK-20

The QMC-CRYOATTK-20 from Quantum Microwave is a Thermalized Cryogenic Attenuator that operates from DC to 40 GHz. It consists of a NiCr on crystal quartz dielectric within a machined OFHC block which renders its thermalizing property. The attenuator has an attenuation of 20 dB with minimal fluctuations with respect to temperature. It can handle an input power of up to 100 mW and has an insertion loss of less than 1 dB.

The QMC-CRYOATTK-20 is available in a gold-plated, silver epoxy-bonded module with 2.92 mm connectors. It has a stackable design and a non-superconducting microstrip pad.
