6. Product Overview
This armored flexible test cable adopts multi-layer shielding and helical steel wire armored structure, featuring excellent compression resistance, bending resistance and ultra-stable amplitude & phase performance. It supports DC~18GHz wide frequency band with 50Ω standard impedance, and is equipped with high-precision N/3.5mm connectors. The cable maintains extremely low signal drift during repeated bending and temperature changes, with a service life of up to 100,000 bending cycles. It is widely applicable for VNA calibration, microwave precision testing, phased array system debugging and other high-frequency measurement scenarios.
