SMA Female to UFL Male Adapter

Description

The SMA Female to U.FL Male Adapter is a specialized “between-series” RF component designed to provide a high-reliability transition between the ubiquitous threaded SMA standard and the ultra-miniature U.FL interface. It features an SMA Jack (Female) on one side, utilizing the standard fine-threaded external interface and internal socket, and a U.FL Male (Plug/Post) on the other, featuring the compact snap-on interface characteristic of the U.FL series.

This adapter is indispensable for engineers and technicians who need to interface standard SMA male cable assemblies or antennas with space-constrained hardware, such as GPS modules, Wi-Fi cards, and IoT sensors. The U.FL interface is designed for extreme high-density applications where PCB real estate is at a premium. Precision-machined to ensure 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 male cables to micro-scale U.FL equipment, bridging the gap between bench-top testing and miniature internal 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 flexible pigtails.

• 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 external cabling while protecting the delicate U.FL snap-on interface.

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

Key Features

• SMA Female to U.FL Male Interface: Consists of an SMA Jack (with socket and external threads) 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 and fragility associated with flexible U.FL pigtail adapters.
