INFO

Introduction to SMA and MCX Connectors
SMA (SubMiniature version A) and MCX (Micro Coaxial) connectors are widely used in RF and high-frequency applications, including telecommunications, aerospace, and IoT devices. These connectors ensure reliable signal transmission while maintaining compact designs. Selecting the right connector and crimping tool is critical for optimal performance.


How to Choose SMA/MCX Connectors

  1. Application Requirements
    • Frequency Range: SMA connectors support up to 18 GHz, ideal for high-frequency systems like radar or 5G. MCX connectors handle up to 6 GHz, suitable for GPS or Wi-Fi.
    • Impedance: Both connectors typically use 50Ω impedance, but verify compatibility with your system.
  2. Size and Space Constraints
    • MCX: Smaller (30% lighter than SMA), perfect for compact devices.
    • SMA: Robust design for industrial or outdoor environments.
  3. Durability and Environment
    • Choose gold-plated SMA connectors for corrosion resistance in harsh conditions.
    • MCX connectors with nickel-plated brass offer cost-effective durability for indoor use.

Recommended Crimping Tools for SMA/MCX Connectors

  1. Precision Crimpers
    • IWISS SN-254B: Adjustable crimping force, compatible with SMA and MCX connectors.
    • Jonard Tools EX-2B: Ergonomic design for repetitive use, includes interchangeable dies.
  2. Stripping and Preparation Tools
    • Huber+Suhner SStrip 1.0: Precision coaxial cable stripper for accurate jacket removal.
    • Paladin Tools PA-1250: Integrated stripper/crimper for quick field repairs.
  3. Affordable Kits
    • Klein Tools VDV226-107: All-in-one kit with crimpers, strippers, and connectors.
    • Amphenol RF Crimp Tool Kit: Includes SMA/BNC/MCX dies for versatility.

Step-by-Step Installation Guide

  1. Strip the coaxial cable to expose the inner conductor and shield.
  2. Insert the connector onto the cable, ensuring proper alignment.
  3. Use a crimping tool to compress the connector’s crimp sleeve uniformly.
  4. Test continuity and signal integrity with a multimeter or VNA.

FAQs About SMA/MCX Connectors

  • Q: Can SMA and MCX connectors be interchanged?
    A: No—they have different sizes and coupling mechanisms.
  • Q: Are crimped connectors reusable?
    A: Crimped connectors are single-use; consider snap-on types for temporary setups.
  • Q: Do I need a special tool for MCX connectors?
    A: Yes—MCX requires a specific die size due to its micro design.
