SMA M for Semi-rigid .141/RG402 Cable

Description

The SMA Male Solder Connector for RG402 is a professional-grade RF component optimized for high-performance signal transmission. Because RG402 features a solid copper outer conductor, this connector utilizes a direct-solder body attachment.

The cable’s outer conductor is soldered 360 degrees directly to the connector body, creating a seamless, gas-tight mechanical and electrical bond. This method eliminates signal leakage and passive intermodulation (PIM) often found in crimp-style connectors. It is the preferred choice for RF power amplifiers, base stations, and laboratory test fixtures operating in the DC to 18 GHz range, where maintaining an ultra-low VSWR is critical.

Key Technical Advantages

• Superior RF Shielding: The direct-solder transition between the cable shield and connector body provides nearly 100% EMI/RFI protection.

• Ultra-Low VSWR: Precision-machined to maintain a strict 50 Ohm impedance path, minimizing signal reflection even at microwave frequencies.

• Maximum Mechanical Bond: The soldered joint ensures the connector remains stable under extreme thermal expansion and high-vibration conditions.

• High Power Handling: The solid metal-to-metal contact allows for better heat dissipation and higher power throughput compared to crimp alternatives.

Key Features

• Direct-Solder Termination: Optimized specifically for the .141″ diameter of semi-rigid and hand-formable cables.

• Teflon (PTFE) Insulator: High-purity dielectric ensures stable electrical performance and high heat resistance during the soldering process.

• Standard 1/4-36 Threaded Nut: Ensures a secure, high-torque connection with any standard SMA female (jack) interface.

• Gold-Plated Center Pin: Provides a low-resistance contact point for precise high-speed signal transmission.

• Broad Frequency Support: Reliably handles signals from DC up to 18 GHz.
