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.
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.
SSMB Connector
SSMB is a miniaturized snap-on coaxial connector smaller than SMB, designed for compact high-frequency assemblies up to 12 GHz. It is used in precision measurement equipment, telecommunications modules, and compact RF assemblies where a small push-on interface is needed at moderate microwave frequencies.
Common Applications
This SMB and SSMB cable assembly is well suited for short pigtails and budget compact RF device connections. The combination of reliable SMB and SSMB 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 – 4 GHz, limited by the lowest-rated component across the cable and connectors.
What is a 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.
