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

Description

The SMA Tee-Type Adapter (Female-Female-Male) is a precision-machined RF component designed to branch a single signal path into two using one standard SMA Male interface and two SMA Female interfaces. This “T-junction” is the preferred choice for modern high-frequency electronics where board space is limited but signal fidelity is paramount. Precision-engineered to maintain signal integrity up to 4 GHz, it is ideal for 4G LTE/5G sub-6GHz prototyping, IoT gateway development, and Software Defined Radio (SDR) applications.

The adapter features a Gold-Plated Brass body for superior conductivity and corrosion resistance, with Gold-Plated center contacts to ensure maximum conductivity and minimal contact resistance. The configuration includes one SMA Male plug (with a 1/4″-36 threaded nut) and two SMA Female jacks. This layout is specifically optimized for mounting directly onto a piece of equipment’s female port (such as an antenna output or a measurement instrument), effectively splitting the signal into two paths for simultaneous data transmission and real-time monitoring.

Key Technical Advantages

• Compact Sub-Miniature Design: Provides high-performance signal branching in a lightweight, small form factor, essential for dense PCB layouts and portable RF equipment.

• Extended Frequency Range: Precision-tuned for operation from DC to 4 GHz, providing low VSWR and consistent 50 Ohm impedance matching across critical wireless communication bands.

• Direct Component Mounting: The single male port allows the adapter to be threaded directly onto female chassis ports or bulkhead connectors, reducing cable bulk and signal path complexity.

• Secure Threaded Coupling: The high-precision threaded interface provides a secure, vibration-resistant connection that maintains electrical stability through at least 500 mating cycles.

• Professional Signal Integrity: High-quality PTFE (Teflon) insulation and precision internal geometry minimize signal reflections and phase distortion in sensitive RF chains.
