SMA Tee-Type Adaptor (F-F-F), DC to 4 GHz

Description

The SMA Tee-Type Adapter (Female-Female-Female) is a precision-machined RF component designed to branch a single signal path into two, or to combine two signals into one, using three standard SMA Female interfaces. The SMA interface is the global standard for high-frequency applications where space is at a premium and electrical performance is critical. This adapter is precision-engineered to maintain low insertion loss and signal integrity up to 4 GHz, making it suitable for IoT development, 4G LTE/5G sub-6GHz prototyping, and advanced RF laboratory environments.

The adapter features a Gold-Plated Brass body for superior conductivity and corrosion resistance, with Gold-Plated center contacts to ensure maximum signal fidelity and minimal contact resistance. The three threaded female interfaces (1/4″-36 thread) provide a secure, high-retention connection with SMA male plugs. This specific F-F-F configuration is most commonly used as a central high-frequency hub to join three SMA male-terminated cables together, allowing for clean signal distribution in dense RF assemblies without the need for additional gender changers.

Key Technical Advantages

• High-Frequency Precision: Rated for operation from DC to 4 GHz, offering excellent VSWR and high return loss for modern wireless communication and high-speed digital signals.

• Triple-Female Versatility: Facilitates the interconnection of multiple SMA male cables, making it an ideal central junction for high-density signal splitting in small enclosures.

• Compact Sub-Miniature Design: Provides high-performance signal branching in a lightweight form factor, essential for space-constrained PCB and module-level testing.

• Threaded Mechanical Stability: The high-precision threaded interface ensures a reliable, vibration-resistant connection that maintains electrical contact through at least 500 mating cycles.

• Low Signal Attenuation: High-quality PTFE (Teflon) insulation and precision internal geometry minimize signal reflections and phase distortion across the entire frequency range.
