About This Assembly
Specs Summary
RG174 Cable
RG-174 is an ultra-thin, highly flexible 50-ohm coaxial cable with a 0.100" outer diameter — one of the smallest coax types available. Its stranded center conductor and single-braid shield make it ideal for tight internal wiring where space is at a premium. Typical uses include GPS antenna pigtails, WiFi module connections, and short adapter leads inside enclosures.
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 GPS and WiFi module pigtails, short flexible adapter leads, and internal device wiring. 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 RG174 coaxial cable used for?
RG-174 is an ultra-thin, highly flexible 50-ohm coaxial cable with a 0.100" outer diameter — one of the smallest coax types available. Its stranded center conductor and single-braid shield make it ideal for tight internal wiring where space is at a premium. Typical uses include GPS antenna pigtails, WiFi module connections, and short adapter leads inside enclosures.
What is the signal loss of RG174?
At 1800 MHz, RG174 has approximately 32 dB of loss per 100 ft (0.32 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 3 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.
