SMA Male to UFL Male Adapter

Description

The SMA Male to U.FL Male Adapter is a specialized “between-series” RF component designed to provide a high-reliability transition between the ubiquitous SMA standard and the ultra-miniature U.FL interface. It features an SMA Plug (Male) on one side, utilizing a standard fine-threaded coupling nut and center pin, and a U.FL Male (Plug/Post) on the other, featuring the sub-miniature snap-on interface typically found on PCB surfaces.

This adapter is indispensable for engineers and technicians who need to connect SMA-terminated hardware?such as spectrum analyzers, signal generators, or high-gain antennas?directly to U.FL-terminated cable assemblies or internal equipment ports. The U.FL interface is designed for extreme space-constrained applications, such as IoT modules, Wi-Fi cards, and mobile devices. Precision-machined to maintain a constant 50 Ohm impedance, it is constructed with a durable gold-plated or nickel-plated brass body and PTFE (Teflon) insulation, maintaining exceptional signal integrity and low VSWR up to 6 GHz.

Key Technical Advantages

• Ultra-Miniature Integration: Enables the direct connection of standard SMA cables to micro-scale U.FL components, bridging the gap between bench-top testing and internal wireless hardware.

• Low Profile Transition: Ideal for test setups where compact U.FL-equipped modules must be integrated into standard SMA test environments without the use of fragile pigtail jumpers.

• Superior RF Shielding: The precision-machined housing provides a continuous ground path, ensuring excellent protection against EMI and RFI interference in sensitive wireless systems.

• Rugged Mechanical Stability: The solid brass housing is designed to handle the mechanical load of the SMA coupling nut while protecting the delicate U.FL snap-on interface.

• Maximum Conductivity: High-purity gold plating on the internal center contact pins ensures ultra-low contact resistance and superior protection against oxidation.

Key Features

• SMA Male to U.FL Male Interface: Consists of an SMA Plug (with center pin and hex coupling nut) and a U.FL Male post (snap-on interface).

• Gold or Nickel-Plated Brass Construction: Offers superior electrical conductivity and professional-grade durability for laboratory and industrial environments.

• Premium PTFE Dielectric: Provides high thermal stability and maintains a constant dielectric constant across its operating frequency range.

• Standard 50 Ohm Impedance: Specifically engineered to match standard high-performance wireless communication and microwave test instrumentation.

• Space-Efficient Design: Provides a direct, rigid transition that eliminates the cable loss associated with flexible U.FL pigtail adapters.
