MMCX Male to SMA Male Adapter

Description

The MMCX Male to SMA Male Adapter is a specialized “between-series” RF component designed to provide a high-reliability transition between two prominent male interface standards. It features an MMCX Plug (Male) on one side, utilizing a micro-miniature snap-on coupling mechanism with a protruding center pin, and an SMA Plug (Male) on the other, featuring a standard hexagonal coupling nut and center pin.

This adapter is essential for engineers and technicians who need to join two female ports?typically connecting an internal MMCX female jack on a wireless module or circuit board directly to an SMA female port on a test instrument, amplifier, or bulkhead. The precision-machined design ensures a constant 50 Ohm impedance and is optimized for high-frequency microwave performance. Constructed with a gold-plated brass body and PTFE (Teflon) insulation, it maintains exceptional signal integrity and low VSWR up to 6 GHz. The snap-on MMCX interface allows for 360-degree rotation, ensuring the connection remains stable without putting torsional stress on delicate micro-miniature components.

Key Technical Advantages

• Direct Series Conversion: Provides a seamless, low-loss transition between micro-scale MMCX and standard SMA standards, eliminating the need for intermediate cable jumpers.

• 360-Degree Rotational Flexibility: The MMCX male interface allows the adapter to rotate freely, preventing mechanical strain and cable binding in high-density electronic layouts.

• Precision RF Shielding: The solid brass construction and gold plating provide a continuous ground path, ensuring excellent protection against EMI and RFI interference.

• Compact & Lightweight: The ultra-slim profile is specifically designed for high-density electronic packaging and portable RF test kits where weight and space are critical.

• Maximum Conductivity: High-purity gold plating on both center contact pins ensures ultra-low contact resistance and superior protection against oxidation in sensitive RF circuits.

Key Features

• MMCX Male to SMA Male Interface: Consists of an MMCX Plug (with center pin) and an SMA Plug (with pin and hex coupling nut).

• Double-Male Configuration: Designed for joining two female ports or jacks in a single, compact housing.

• Gold-Plated Brass Construction: Offers the highest level of electrical performance and corrosion resistance required for precision microwave applications.

• Premium PTFE Dielectric: Offers high thermal stability and maintains consistent electrical performance across high-frequency bands.

• Industrial Durability: Rated for at least 500 mating cycles, ensuring long-term reliability for laboratory testing and field integration.
