SMP Female RF Coaxial Connector – For 2# Semi-Rigid / Semi-Flexible Cable

SMP Female RF Coaxial Connector – For 2# Semi-Rigid / Semi-Flexible Cable

Model: SMP-KWB2-3

Product Overview

The SMP series is an ultra-miniature, push-on/self-locking RF coaxial connector system designed for high-frequency, high-density applications. It allows for a degree of axial and radial float, making it ideal for blind mating between PCBs, chassis, and modules. The SMP interface supports secure, fast connections with excellent mechanical and electrical performance.

Applications
Commonly used in communication base stations, radar systems, aerospace equipment, and RF cable assemblies requiring compact, high-frequency interconnects.

Key Features

•     SMP female interface compatible with 2# semi-rigid or semi-flexible coaxial cables
•     Ultra-compact size suitable for dense modular systems
•     High-frequency performance and superior signal integrity
•     Allows axial and radial misalignment for blind-mating capability
•     Excellent vibration resistance and mechanical reliability
•     Easy to solder and integrate into cable assemblies or submodules
