Phase-Track PFlex Cable Assemblies

Home > Products > Assemblies > Phase Critical Assemblies > Phase Track Pflex Cable Assemblies

 

 

Times Microwave TF4 dielectric material is the key ingredient, making our PhaseTrack products the best choice for phase critical interconnect applications. 

 

PhaseTrack cable dielectric has been developed to eliminate the "PTFE knee" in the phase/temperature performance of PTFE-based cables for phase-critical applications.  

 

The PhaseTrack PFlex product line consists of flexible cables similar to the TMS TFlex cables, but using the TF4 dielectric material for superior phase performance. PFlex is designed primarily for use "in-the-box," often instead of semi-rigid cables.

 

 

PFlex cables use a lightweight shield combining helical and wire braid technologies:
