Specs Summary
RG405_BLUE Cable
RG-405 Blue is the color-coded variant of RG-405, offering the same 0.086" semi-rigid construction with a blue outer jacket for easy identification. Used in dense microwave assemblies and lab environments where distinguishing individual cables at a glance is critical to efficient operation.
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.
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 MMCX and SMA cable assembly is well suited for color-identified compact lab and microwave assemblies. The combination of reliable MMCX 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.
