Frequently Asked Questions
What makes the PS460L-32G-F suitable for 32GHz phase-critical applications?
The cable utilizes Low-Density PTFE (LD-PTFE) dielectric combined with a dual-shield structure (flat SPC strip plus SPC braid). This configuration minimizes velocity variations during mechanical flexing, maintaining a phase stability of ±0.3 °/GHz.
How does the FEP jacket perform in harsh environments?
The high-grade Gray FEP jacket offers an operating temperature range of -55°C to +165°C, high resistance to chemicals, UV exposure, and moisture ingress, making it suitable for aerospace, defense, and demanding test environments.
How to calculate attenuation at custom frequencies?
Attenuation at any frequency (F in MHz) can be calculated using the coefficient formula: IL = 0.81650 * sqrt(F_MHz) + 0.00088 * F_MHz in dB/100m.
