TNC Female to SMA Male Adapter

Description

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

This adapter is indispensable for engineers and technicians who need to connect TNC male-terminated cables?common in outdoor antennas, avionics, and cellular base stations?to SMA female ports found on spectrum analyzers, signal generators, and small-form-factor RF components. The TNC interface provides superior mechanical stability compared to bayonet-style connectors, while the SMA side ensures precision microwave performance. Constructed with a heavy-duty nickel-plated brass body and PTFE (Teflon) insulation, it ensures exceptional signal integrity and low VSWR up to 11 GHz, making it ideal for both permanent field installations and high-frequency laboratory measurements.

Key Technical Advantages

• Standard-to-Rugged Bridge: Enables the direct connection of ruggedized TNC cables to high-precision SMA equipment without the need for flexible cable jumpers.

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

• Superior RF Shielding: The solid brass construction and precision machining 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.

Key Features

• TNC Female to SMA Male Interface: Consists of a TNC Jack (with socket and external threads) and an SMA Plug (with center pin and hex coupling nut).

• Nickel-Plated Brass Construction: Offers superior corrosion resistance and professional-grade durability for indoor and outdoor RF environments.

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