RG-316 DS Cable

Description

RG-316 DS is the high-performance, double-shielded variant of the standard RG-316. The “DS” designation indicates the addition of a second silver-plated copper braid, which significantly enhances the cable’s shielding effectiveness (typically improving RF isolation by an additional 20-30 dB over single-shielded versions). This makes it indispensable for high-density electronic environments where preventing signal crosstalk and EMI is paramount.

The core of the cable features a 7/34 stranded silver-plated copper-clad steel (SPCCS) center conductor, offering superior mechanical strength and vibration resistance. Combined with a high-stability PTFE (Teflon) dielectric, it maintains exceptional signal integrity and low attenuation into the microwave frequency range. Encased in a durable, high-temperature FEP (Fluorinated Ethylene Propylene) jacket, RG-316 DS operates reliably in extreme temperatures ranging from -55°C to +200°C. It is most commonly terminated with high-precision SMA, SMB, or MCX connectors for use in demanding RF systems.

Key Technical Advantages

• Superior Double Shielding: Two layers of silver-plated copper braid provide a robust barrier against electromagnetic interference (EMI) and significantly reduce signal leakage.

• Extreme Thermal Stability: The all-Teflon construction (PTFE/FEP) ensures the cable remains electrically and physically stable in extreme heat or cryogenic conditions.

• Rugged Flex Life: The stranded SPCCS conductor is designed to withstand repeated flexing and high-vibration environments without work-hardening or signal degradation.

• Enhanced RF Isolation: Specifically optimized for dense equipment racks where multiple high-frequency signals are routed in close proximity.

• Silver-Plated Signal Path: Silver plating on both the internal conductor and the dual shields maximizes conductivity via the “skin effect” and prevents performance loss due to oxidation.
