MMCX F Solder for Semi-rigid .086/RG405 Cable

Description

The MMCX (Micro-Miniature Coaxial) female connector is a high-performance RF component valued for its exceptionally small footprint and its ability to maintain superior signal integrity at microwave frequencies. This variant is specialized for the .086-inch cable class, specifically optimized for solid-jacket Semi-Rigid and hand-formable RG405 cables. The snap-on coupling mechanism allows for a secure yet rotatable connection, which is essential for relieving mechanical stress in rigid cable assemblies within tight enclosures.

This connector utilizes a direct-solder termination for both the center contact and the outer jacket. By soldering the cable’s copper jacket directly into the precision-machined rear bore of the gold-plated connector body, the assembly achieves an airtight, 360-degree electrical bond. This method is superior for maintaining maximum shielding effectiveness and ensuring the lowest possible VSWR in high-frequency applications where cable diameter must be minimized. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable operation up to 6 GHz.

Key Technical Advantages

• Direct-Solder Integrity: The solder-on body interface creates a continuous metallic shield with the cable jacket, providing maximum EMI/RFI protection essential for sensitive microwave systems.

• Precision .086/RG405 Match: Specifically calibrated for the 0.086-inch OD jacket, ensuring an optimized electrical transition and high mechanical rigidity for small-form-factor applications.

• Micro-Miniature Snap-On Design: The ultra-compact interface enables high-density packaging on PCBs and within modular RF housings where space is extremely limited.

• Phase-Stable Performance: The permanent solder bond minimizes signal fluctuations and non-linearities, making it ideal for precision micro-jumpers and internal equipment routing.

• Superior Conductivity: Features heavy gold plating on the body and center contact to ensure low contact resistance and long-term protection against oxidation.
