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.
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.
SMA Connector
SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.
Common Applications
This QMA and SMA cable assembly is well suited for short pigtails and budget compact RF device connections. The combination of reliable QMA and SMA 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 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.
