Model Comparison & Selection Note
Compared to our solid-PTFE variant (PS160L-110G-F), the PS160L-110G-BF utilizes an advanced Micro-Porous LD-PTFE dielectric. This provides a higher velocity of propagation (76% vs 70%), lower dielectric loss (attenuation reduced by ~14% at 18GHz), tighter phase stability vs bending (±0.2°/GHz vs ±0.3°/GHz), and an expanded operating temperature ceiling (up to +165℃).
Frequently Asked Questions
How does PS160L-110G-BF achieve higher propagation velocity than standard 160-size cables?
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.
What is the main difference between PS160L-110G-BF and PS160L-110G-F?
The “BF” suffix denotes a micro-porous LD-PTFE dielectric with enhanced temperature rating (-55 to +165℃) and lower attenuation, whereas the “F” suffix utilizes solid PTFE rated to +125℃.
What is the bend radius limit for installation?
The minimum static bend radius is 8.0 mm, while the dynamic bend radius for repeated flexure is 16.0 mm.
