In the fast-paced world of telecommunications, RF testing, and industrial IoT, signal integrity is non-negotiable. Enter the RG316 SMA to BNC coaxial cable assembly from SigmaRF—a high-performance interconnect solution engineered for precision and durability in the toughest environments. This assembly isn't just a cable; it's a reliable bridge for RF signals in applications ranging from medical devices and automotive systems to GPS tracking, drone testing, and beyond.

At SigmaRF, we craft these assemblies with premium materials and rigorous testing to deliver low signal loss, superior shielding, and long-term reliability. The RG316 cable, a silver-plated coaxial powerhouse, excels in high-frequency scenarios, supporting stable performance across broad spectrums. Its double-shielded design minimizes electromagnetic interference (EMI), ensuring clean signals even in noisy industrial settings. Thanks to its compact diameter and flexible PTFE insulation, it bends and routes effortlessly in tight spaces—like drone payloads, RF enclosures, or compact medical gear.

What sets this assembly apart are the connectors and termination excellence. The SMA connector (available in male or female) offers vibration resistance and repeatable connections up to microwave frequencies, making it a staple for demanding RF setups. Paired with the BNC's quick bayonet-style lock, it's perfect for lab instruments and test equipment. We use precision crimping for scalable production or high-quality soldering for superior electrical contact—every unit undergoes testing for optimal 50-ohm impedance matching and minimal return loss.

Diving into specs: RG316 features a silver-plated copper conductor, PTFE dielectric, and silver-plated copper braid shielding, all tolerating wide temperature swings for industrial resilience.

Customization is our edge. Choose standard lengths or tailor to drawings, mix connector types, add labels or sleeves, and scale from prototypes to high-volume runs. SigmaRF's RG316 SMA to BNC assemblies empower engineers to tackle modern RF challenges with confidence—whether standard or bespoke.
