MMCX-KF/2.9 RF head
Key Designators

• MMCX: Stands for Micro-Miniature Coaxial. These are subminiature, lightweight RF connectors featuring a snap-on coupling mechanism allowing for 360-degree rotation. Standard MMCX connectors traditionally function from DC to 6 GHz at 50 Ohms impedance. 
• KF: In industry part-number coding, "K" frequently denotes the 2.92mm (K-type) precision microwave interface, while "F" stands for Female (Jack). 
• 2.9: Refersexplicitly to the 2.92 mm outer conductor dimension used in millimeter-wave applications. Precision 2.92mm connectors are rated to operate mode-free up to 40 GHz. 

Typical ApplicationsThese components are primarily deployed in advanced testing assemblies and high-frequency communication environments, including:

• High-speed instrumentation and RF matrix routing.
• Military avionics and radar sub-assemblies.
• Converting internal ultra-dense PCB routing inputs (via MMCX) into high-frequency test ports (2.92mm).
