MCX connectors (Micro Coaxial) are miniature RF connectors used for high-frequency signal connections up to 6 GHz. They feature a snap-on coupling mechanism, providing quick and secure connections. Due to their small size and reliable performance, MCX connectors are commonly used in GPS devices, wireless communication systems, and other compact electronic applications. They are known for their ease of use, durability, and ability to maintain good signal integrity in tight spaces.
