Equipment and Components for the RF and Microwave industry

High Velocity Ultra Low Loss
Test Cables
ACH-CA18, ACH-CA26 & ACH-CA40/-CA50 Series


  • Frequency DC-18GHz, DC-26.5GHz & DC-40GHz/DC-50GHz
  • Ultra Low Loss
  • Fast Velocity Propagation
  • Low Dielectric Constant
  • Excellent Phase Stability
  • RoHS Compliant

 

AtlanTecRF's ACH series of high velocity ultra low loss test cable assemblies are designed for general purpose use with laboratory and test equipment applications where low loss, flexibility, high performance and affordability are key features.

The high Vp of these cables offers improved phase stability over lower Vp types. Connectors are either SMA, 2.92mm or 2.4mm male with passivated stainless steel bodies. Standard stock lengths range from 0.5 to 2.0 metres but custom cable lengths are also available to order.
