Cross Reference & Form-Fit-Function Alternative
PS520L-25G-F serves as a direct form-fit-function alternative for standard 0.200-inch diameter high-frequency, phase-stable microwave cables requiring low-loss propagation up to 25 GHz with a chemical and thermal resistant FEP outer jacket.
Frequently Asked Questions
What makes the PS520L-25G-F suitable for high-frequency RF applications?
The combination of a solid Silver Plated Copper conductor, low-density PTFE (LD-PTFE) insulation, and a dual shielding design (self-adhesive aluminum foil plus silver-plated copper braid) ensures ultra-low insertion loss and stable phase performance up to 25 GHz.
How does the FEP jacket compare to TPU/PUR jackets in the PS520 series?
The blue Fluorinated Ethylene Propylene (FEP) jacket (-F) provides superior thermal performance (-55°C to +85°C), high chemical resistance, and excellent dielectric properties compared to flexible PUR/TPU options (-P), making it ideal for demanding environmental conditions.
What is the minimum bend radius requirement for installation?
The static minimum bend radius is 26.00 mm for fixed installations, while the dynamic minimum bend radius for flexible or repetitive bending applications is 53.00 mm.
