MMCX Jack to SMA Female Adapter [RFS-100178]

MMCX Jack to SMA Female Adapter [RFS-100178]

The MMCX Jack to SMA Female Adapter bridges the ultra-compact MMCX connector world with the standard SMA interface, enabling miniaturized RF modules, PCB-mounted MMCX ports, and compact wireless devices to connect to SMA-terminated cables and test instruments. Operating at 50 Ohm impedance, this adapter is invaluable in RF development, prototyping, and small-form-factor wireless system integration. The MMCX jack (female) end features the snap-on coupling mechanism distinctive of the Micro-Miniature Coaxial connector family - a locking interface that provides 360° rotation after mating, ideal for applications where cable orientation must be adjusted without unmating. The SMA female end accepts a standard SMA male plug from test cables, signal generators, or spectrum analyzers, providing easy access to bench-top RF instrumentation from an MMCX-equipped device. This adapter is frequently used during the development and testing of IoT devices, embedded wireless modules, GPS receivers, and compact radio systems that employ MMCX ports. Constructed from gold-plated brass with PTFE dielectric, this adapter delivers low insertion loss and reliable signal transfer from DC through several gigahertz, supporting precise RF characterization of compact wireless devices.
