Cross Reference & Direct Equivalent Replacement
The PS1200L-10G low loss phase stable coaxial cable is engineered as a direct drop-in replacement for Times Microwave SFT226 / SFT-226, delivering matched 10 GHz high-frequency capability, identical mechanical dimensions (12.00 mm outer diameter), and equivalent phase stability under flexure.
Frequently Asked Questions
How does the 7/1.17 mm stranded inner conductor affect phase stability and mechanical fatigue during repeated flexure?
The 7/1.17 mm stranded silver-plated copper conductor provides significantly superior dynamic flexibility and fatigue resistance compared to solid conductors of equivalent size. Combined with expanded LD-PTFE insulation, this construction minimizes internal strain concentration during movement, maintaining consistent phase linearity (±0.2 °/GHz) and low VSWR throughout repeated dynamic bending.
Why is the PS1200L-10G ideal as a direct drop-in replacement for Times Microwave SFT226?
PS1200L-10G strictly matches the key electrical and physical parameters of SFT226, including 12.00 mm nominal outer diameter, 50 Ω impedance, 76% velocity of propagation, and identical attenuation constants (K1=0.39168, K2=0.0006). It allows seamless drop-in integration into existing system layouts without requiring redesigns of cable routing, mounting clamps, or RF connector termination tooling.
How does the triple-layer shield structure achieve >90 dB screening effectiveness at 10 GHz?
The shielding architecture utilizes a helically wrapped silver-plated copper strip as the inner shield for 100% optical coverage, a high-temperature aluminum foil interlayer to prevent inter-layer friction and signal leakage, and a high-density silver-plated copper wire braid on the outside. This combination effectively eliminates RF radiation and cross-talk across the entire DC to 10 GHz spectrum.
