TR Multicoax Series

Ganged Coaxial Attenuator

High density thermalized low noise cryogenic bulkhead attenuator array for use with TR Multicoax™ connectors. Utilizes industry leading materials like Oxygen-free high thermal conductivity (OFHC) copper and NiCr on thermally conductive crystalline quartz dielectric provides minimal change in attenuation with temperature delta. Attenuation is offered in 0, 10, and 20 dB configurations and supports bandwidth up to 12 GHz. 16 channel form factor at a 2.54 mm pitch, signal to signal, saves valuable real estate in confined spaces.

Benefits Include:

  • Small form factor for space constrained environments
  • Ideal for quantum computing applications
  • Multiple attenuation values available for experimentation
  • Substantial channel increase over traditional surface mount connectors
  • Minimal change in attenuation with temperature


  • Dilution refrigerators
  • Cryogenic devices
  • Quantum computing
  • Vacuum chambers
  • Defense/Aerospace
