TNC Male to SMA Male Adapter

Description

The TNC Male 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, precision SMA interface. It features a TNC Plug (Male) on one side, utilizing a rugged threaded coupling nut and center pin, 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 two female-terminated components directly-typically bridging a TNC female bulkhead port on a ruggedized enclosure to an SMA female port on a laboratory instrument or microwave module. The TNC side provides superior mechanical stability compared to bayonet-style connectors, while the SMA side ensures the precision microwave performance required for modern high-frequency systems. Constructed with a heavy-duty nickel-plated brass body and PTFE (Teflon) insulation, it maintains exceptional signal integrity and low VSWR up to 11 GHz, making it ideal for both permanent field installations and high-frequency test environments.

Key Technical Advantages

• Direct Dual-Male Bridge: Enables the secure, direct connection between TNC female and SMA female ports, eliminating the need for intermediate cable assemblies.

• Vibration-Proof Connectivity: The threaded TNC interface ensures a stable, locked connection that resists loosening due to mechanical shock or movement in mobile and aerospace 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 both internal center contact pins ensures ultra-low contact resistance and superior protection against oxidation.

Key Features

• TNC Male to SMA Male Interface: Consists of a TNC Plug (with center pin and threaded nut) 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.
