Frequently Asked Questions
How does microporous LD-PTFE dielectric achieve low loss and phase stability up to 50 GHz?
Micro-porous Low-Density PTFE (LD-PTFE) introduces uniformly distributed micro-voids into the dielectric matrix. This reduces the effective relative permittivity ($\epsilon_r$) to achieve 76% velocity of propagation (VoP), drastically reducing dielectrical loss and mitigating phase variations caused by thermal changes and mechanical flexure.
Why is the “-F” FEP jacket preferred over PUR for 50 GHz high-temperature applications?
The Fluorinated Ethylene Propylene (FEP) outer jacket (“-F” designation) provides an extended operating temperature range from -55℃ to +165℃, lower outgassing, and exceptional resistance to environmental degradation compared to polyurethane (PUR), making it essential for high-reliability aerospace, defense, and laboratory test setups.
What shielding efficiency does the silver-plated tape and braid structure provide?
The combination of a silver-plated copper strip inner shield and a silver-plated copper wire outer braid provides continuous 360-degree shielding with screening effectiveness exceeding 90 dB up to 50 GHz, virtually eliminating RF crosstalk and radiation leakage in dense multi-channel systems.
