In phased-array antennas, multi-channel RF front-ends, and advanced Test & Measurement setups, differences in electrical length between cables can directly degrade beamforming accuracy, measurement repeatability, and overall system performance. Even minor phase errors between channels can shift beam patterns, distort S-parameter results, or mask the DUT’s actual behavior.

WithWave phase-matched cable assemblies are designed to minimize these mismatches by controlling electrical length, delay, and phase within a specified tolerance across all channels in a set. Using high-quality coaxial structures and precision manufacturing, our Precision Test and Low Loss & Flexible cable families can be supplied as phase-matched sets, enabling engineers to build multi-channel test fixtures and RF subsystems with predictable, repeatable phase relationships.
