About This Assembly
Specs Summary
RFC100A Cable
RFC-100A is a cost-effective thin 50-ohm coaxial cable equivalent in size to LMR-100A, offering solid performance for short internal connections and pigtails at a lower price point. A practical choice for budget-conscious builds where cable runs are under 10 feet, such as WiFi module connections, GPS pigtails, and compact RF assemblies.
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.
QMA Connector
QMA is a quick-mate RF connector that provides the electrical performance of Type N up to 18 GHz with a faster quarter-turn locking mechanism instead of full threading. It is widely deployed in cellular base station cabinets, DAS installations, and equipment racks where rapid cable changes are required without sacrificing electrical performance.
Common Applications
This MMCX and QMA cable assembly is well suited for short pigtails and budget compact RF device connections. The combination of reliable MMCX and QMA 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 RFC100A coaxial cable used for?
RFC-100A is a cost-effective thin 50-ohm coaxial cable equivalent in size to LMR-100A, offering solid performance for short internal connections and pigtails at a lower price point. A practical choice for budget-conscious builds where cable runs are under 10 feet, such as WiFi module connections, GPS pigtails, and compact RF assemblies.
What is the signal loss of RFC100A?
At 1800 MHz, RFC100A has approximately 24.5 dB of loss per 100 ft (0.245 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 6 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.
