SMP Male Light Hole RF Coaxial Connector – PCB Solder Type
Product Overview
The SMP connector is an ultra-miniature, push-on/self-locking RF coaxial connector designed for high-frequency, high-density modular applications. It features compact size, lightweight construction, wide frequency range, and strong resistance to vibration. Its mechanical design allows for limited axial and radial misalignment, making it ideal for blind mating in densely packed systems.
Applications
Commonly used in matrix antennas, radar systems, aerospace electronics, communication modules, and other RF applications requiring compact, high-reliability connections.
Key Features
Light detent (snap-in) interface for easy mating/unmating
Designed for PCB soldering (typically through-hole)
Ultra-compact and lightweight for high-density layouts
Long mechanical life and excellent electrical performance
Supports wide frequency bandwidth (up to 40 GHz depending on design)
Allows limited axial and radial float for flexible integration
