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.
MCX Connector
MCX (Micro Coaxial) is a snap-on RF connector approximately 30% smaller than SMB, designed for compact equipment requiring frequent connections in a small footprint. Rated to 6 GHz, MCX is commonly used in GPS receivers, automotive telematics modules, handheld communication devices, and compact measurement instruments.
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 MCX and SMB cable assembly is well suited for short pigtails and budget compact RF device connections. The combination of reliable MCX 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.

| 2.4 GHz | 29 dB | 0.29 dB |
| 5.8 GHz | 49 dB | 0.49 dB |
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 – 4 GHz, limited by the lowest-rated component across the cable and connectors.
What is a MCX connector?
MCX (Micro Coaxial) is a snap-on RF connector approximately 30% smaller than SMB, designed for compact equipment requiring frequent connections in a small footprint. Rated to 6 GHz, MCX is commonly used in GPS receivers, automotive telematics modules, handheld communication devices, and compact measurement instruments.
