VN Series VNA Test Port Extension Cables
High-Performance VNA Test Port Extension Cables for Accurate, Repeatable Measurements
MegaPhase VN Series VNA Test Port Extension Cables are engineered for demanding RF and microwave test environments where measurement accuracy, phase stability, and long-term durability are critical. Available in configurations supporting frequencies through 67 GHz, these high-performance cable assemblies provide mechanically stable, precision performance for vector network analyzer (VNA) testing, calibration, and production measurement applications.
Designed with an internal armor reinforcement, VN Series cables maintain exceptional electrical stability during flexure, helping engineers achieve repeatable measurements while minimizing test uncertainty. Whether used in laboratory characterization, automated test systems, or high-frequency production environments, VN Series cables deliver reliable performance over thousands of test cycles. Custom lengths and phase-matched sets are available.

Why Engineers Choose the VN Series
Exceptional Phase Stability
Accurate VNA measurements depend on stable cable performance. VN Series cables are designed to minimize changes in phase, insertion loss, and VSWR during flexure, helping maintain calibration integrity and reducing measurement drift.
Repeatable Measurements Over Time
Mechanical movement is one of the leading causes of measurement variation in RF test systems. The VN Series is specifically engineered to deliver highly repeatable electrical performance, allowing engineers to trust their data and reduce retesting.
Rugged Design for Demanding Test Environments
Internally armored construction and reinforced cable ends provide superior durability compared to conventional test cables. The result is a longer service life and lower total cost of ownership in both laboratory and production environments.
Customizable for Your Test Setup
Available in custom lengths, phase-matched configurations, and a wide range of precision connector interfaces, VN Series cables can be tailored to meet the requirements of virtually any RF measurement system.
