Frequently Asked Questions
Why is a 2.30mm outer diameter preferred for 67 GHz V-Band / 1.85mm connector terminations?
Operating up to 67 GHz requires avoiding higher-order waveguide modes within the coaxial structure. A 2.30mm outer diameter allows optimal dielectric dimensions (1.55mm) matching 1.85mm connector geometries, minimizing return loss and VSWR spikes at mmWave frequencies.
How does microporous LD-PTFE dielectric maintain dynamic phase tracking up to 67 GHz?
Micro-porous Low-Density PTFE (LD-PTFE) achieves a 76% velocity of propagation (VoP) by replacing dense solid PTFE with controlled micro-air pockets. This significantly reduces dielectric constant variations under physical bending and thermal changes, keeping phase variance under ±0.2 °/GHz.
What is the advantage of using a silver-plated copper strip inner shield combined with a wire braid?
The helically wrapped silver-plated copper strip provides seamless 100% inner coverage to suppress microwave leakage, while the outer braid delivers structural integrity and flexible ground grounding. Together, they guarantee over 90 dB screening effectiveness across the entire 67 GHz bandwidth.
