TNC Female to SMA Female Adapter

Description

The TNC Female to SMA Female 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 Jack (Female) on one side, utilizing a rugged threaded external housing and internal socket, and an SMA Jack (Female) on the other, featuring a standard fine-threaded external interface and internal socket.

This adapter is indispensable for engineers and technicians who need to connect two male cable assemblies directly?typically joining a heavy-duty TNC male cable to a high-precision SMA male test lead or antenna. Unlike standard BNC connectors, the threaded TNC interface ensures that the connection remains secure and signal integrity is maintained even in environments subject to significant mechanical shock and movement. 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, bridging the gap between field-grade infrastructure and laboratory instrumentation.

Key Technical Advantages

• Cross-Series Gender Bridge: Enables the direct connection of TNC male and SMA male connectors, eliminating the need for complex intermediate cable jumpers.

• Vibration-Proof Stability: The threaded TNC female interface provides a locked, stable connection that resists loosening in mobile, aerospace, and industrial 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 sockets ensures ultra-low contact resistance and superior protection against oxidation.

Key Features

• TNC Female to SMA Female Interface: Consists of a TNC Jack (with socket and external threads) and an SMA Jack (with socket and external threads).

• 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.

• Industrial Durability: Rated for at least 500 mating cycles, ensuring long-term reliability in laboratory, industrial, and tactical settings.

• Precision 50 Ohm Match: Specifically engineered to match standard high-performance wireless communication and microwave test instrumentation.
