SMA Female to TNC Male Adapter

Description

The SMA Female to TNC Male Adapter is a specialized “between-series” RF component designed to provide a high-reliability transition between the ubiquitous threaded SMA standard and the vibration-resistant TNC interface. It features an SMA Jack (Female) on one side, utilizing a standard fine-threaded external interface and internal socket, and a TNC Plug (Male) on the other, featuring a threaded coupling nut and center pin.

This adapter is indispensable for engineers and technicians who need to connect SMA male cable assemblies or antennas to TNC female ports found on ruggedized radios, avionics, and cellular base stations. The TNC interface provides a more secure, threaded connection compared to the bayonet-style BNC, making it ideal for environments subject to mechanical shock and movement. Precision-machined to ensure a constant 50 Ohm impedance, it is constructed with a durable nickel-plated brass body and PTFE (Teflon) insulation, maintaining exceptional signal integrity and low VSWR up to 11 GHz.

Key Technical Advantages

• Standard-to-Rugged Integration: Enables the direct connection of high-precision SMA cables to heavy-duty TNC infrastructure without the need for flexible jumpers.

• Vibration-Proof Connectivity: The threaded TNC male interface ensures a secure, stable link that resists loosening in industrial and mobile applications.

• Superior RF Shielding: The solid brass construction and high-quality plating provide a continuous ground path, ensuring maximum protection against EMI and RFI interference.

• Precision-Machined Threads: Features high-quality threading on both interfaces to ensure smooth, secure connections and prevent port damage during high-frequency use.

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