Q Rate Coax and Twinax Cable Assemblies feature rugged, high-performance Edge Rate contacts and an integral metal power/ground plane which provide for superior electrical performance. 

Q Rate Coax Cable (EQRD Series) is a 50Ω single-ended 34 AWG micro coax ribbon cable system with a choice of 26, 52 or 78 contacts per row and a standard rugged friction lock. Performance is 4 Gbps at 1 meter. Q Rate Twinax Cable (EQRP Series) is a 100Ω differential pair 30 AWG twinax ribbon cable system available in 18, 36 or 54 pairs. Performance is almost 10 Gbps at 1 meter.

The 0.8 mm (0.0315") pitch cables mate with Samtec's high performance, slim-body Q Rate socket and terminal strips (QRF8/QRM8 Series). Mated heights of 11.5 mm or 14.45 mm and overall cable lengths from 95.3 mm (3.75") to 1 meter (40") are standard. Optional screw downs, as well as application specific sizes, cable lengths, terminations and wire gauges are also available.

Q Rate Connectors and Cable assemblies use Samtec's Edge Rate contacts. Edge Rate contacts are designed specifically for excellent electrical performance and durability. A smooth-milled contact design provides for low insertion/withdrawal force, allowing "zippering" during unmating. The positioning of the contacts relative to the ground plane results in superior signal integrity while the contact design reduce broadside coupling and crosstalk.
