Key Cable Considerations:

• Impedance: Typically 50Ω, matching the impedance of most RF systems to ensure optimal phase and signal integrity.
• Dielectric Material: High-quality Teflon or foam dielectric materials are used for phase stability and to prevent signal attenuation.
• Shielding: Proper shielding, usually braided or foil shields, ensures that external electromagnetic interference does not affect the signal or phase.
• Mechanical Stability: The cable design ensures that the physical stress on the cable (e.g., bending, tension) does not cause phase drift or signal degradation.
