The JARON Ultra-Flex Series RF Cable Assembly is engineered with ultra-flexible shielding and phase-stable conductors to deliver consistent amplitude and phase performance under repeated bending and dynamic testing conditions. Supporting DC–40 GHz operation, it features low insertion loss, low reflection, and superior mechanical endurance, making it ideal for dense test benches, production platforms, and calibration systems. With an anti-fatigue jacket and a minimum bend radius up to one-third that of conventional cables, it ensures reliable, repeatable RF connections for demanding high-frequency environments.
