About This Assembly

RG405 Cable

RG-405 (UT-085) is a 0.086" semi-rigid coaxial cable — smaller than RG-402 — with a solid copper outer conductor delivering superior shielding and phase stability. Commonly used in microwave integrated circuit (MMIC) assemblies, millimeter-wave test setups, and anywhere an extremely compact rigid interconnect is required up to 65 GHz.

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 SMA cable assembly is well suited for compact microwave and millimeter-wave assemblies and MMIC interconnects. The combination of reliable 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.
