Cross Reference & Form-Fit-Function Alternative
PS360LS-40G-F is a direct form-fit-function replacement for standard 0.160-inch flexible 40GHz phase-stable cables requiring high flexure durability (stranded inner conductor) and temperature resistance up to +125°C.
Frequently Asked Questions
What is the structural advantage of the ‘S’ designation in PS360LS-40G-F?
The ‘S’ designation denotes a stranded inner conductor construction (7/0.31 mm) rather than a solid core, providing enhanced dynamic flexibility, better resistance to mechanical fatigue during repeated flexure, and improved installation durability.
How does PS360LS-40G-F maintain electrical stability up to 40 GHz?
It utilizes a low-density PTFE (LD-PTFE) dielectric coupled with a dual shielding system consisting of a self-adhesive aluminum foil and a silver-plated copper wire braid, delivering >90 dB shielding effectiveness and a 76% velocity of propagation.
What operating environment is suitable for the FEP jacket?
The blue FEP jacket (-F) offers exceptional thermal endurance from -55°C to +125°C, high chemical inertness, and mechanical toughness suitable for demanding aerospace, defense, and high-frequency test bench applications.
