Abstract

Coaxial cables are vital to a wide range of electronic systems.
Phase accuracy in coaxial cables is sensitive to the
inevitable cable bending in actual usage and temperature
change in the environment. For phase-critical applications,
e.g. multi-antenna channel sounding, phase accuracy is
fundamental to obtain trustworthy measurement results. A
technique to track and remove random phase change in
coaxial cables due to cable effect is presented. The phasestabilizing
technique provides a general phase stabilizing
framework via introducing a bi-directional transmission on
the cable. The principle of the phase stabilizing scheme is
explained and its effectiveness is experimentally validated
in a back-to-back measurement.
