About This Assembly
Specs Summary
RG316DS Cable
RG-316DS is a double-shielded version of RG-316, featuring two braid layers over the PTFE dielectric for superior EMI isolation. This construction reduces signal leakage and interference pickup, making it essential in sensitive receiver chains, spectrum analyzers, and high-density RF wiring where crosstalk must be minimized.
MMCX Connector
MMCX (Micro-Miniature Coaxial) is one of the smallest RF connectors in common use, featuring a snap-lock mechanism rated to 6 GHz. Its tiny size makes it essential for embedded WiFi and Bluetooth modules, wearable devices, hearing aids, and any RF assembly where board space is extremely constrained. It is the standard interface on most M.2 WiFi cards.
SMB Connector
SMB (SubMiniature version B) is a snap-on RF connector with a simple push-on coupling rated to 4 GHz. Its ease of mating and small footprint make it popular in telecommunications equipment, set-top boxes, GPS timing receivers, and instrumentation where a secure but easily disconnected interface is needed.
Common Applications
This MMCX and SMB cable assembly is well suited for sensitive receiver chains, spectrum analyzer inputs, and high-EMI environments. The combination of reliable MMCX and SMB connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.

Frequently Asked Questions
What is RG316DS coaxial cable used for?
RG-316DS is a double-shielded version of RG-316, featuring two braid layers over the PTFE dielectric for superior EMI isolation. This construction reduces signal leakage and interference pickup, making it essential in sensitive receiver chains, spectrum analyzers, and high-density RF wiring where crosstalk must be minimized.
What is the signal loss of RG316DS?
At 1800 MHz, RG316DS has approximately 26 dB of loss per 100 ft (0.26 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 4 GHz, limited by the lowest-rated component across the cable and connectors.
What is a MMCX connector?
MMCX (Micro-Miniature Coaxial) is one of the smallest RF connectors in common use, featuring a snap-lock mechanism rated to 6 GHz. Its tiny size makes it essential for embedded WiFi and Bluetooth modules, wearable devices, hearing aids, and any RF assembly where board space is extremely constrained. It is the standard interface on most M.2 WiFi cards.
