BNC Female to SMA Male Adapter

Description

The BNC Female to SMA Male Adapter is a high-precision between-series RF component designed to bridge standard BNC connections with sub-miniature SMA interfaces. It features a BNC Jack (Female) on one side, allowing for quick-connect bayonet mating, and an SMA Plug (Male) on the other, featuring a standard hexagonal coupling nut and center pin.

This adapter is widely used in telecommunications and RF testing where equipment with BNC outputs must interface with SMA-terminated cables or high-frequency devices. Its compact, precision-machined design ensures a constant 50 Ohm impedance, significantly reducing signal reflections and power loss. Constructed with a heavy-duty nickel or gold-plated brass body and PTFE (Teflon) insulation, it maintains exceptional signal integrity and low VSWR up to 4 GHz. The rugged build is optimized for frequent mating cycles in both field operations and laboratory environments.

Key Technical Advantages

• Direct Series Conversion: Provides a seamless, low-loss transition between BNC and SMA standards, eliminating the need for bulky custom cable assemblies.

• Precision Threaded Interface: The SMA male side features a high-strength hexagonal nut for secure, vibration-proof mating with female jacks.

• Quick-Connect Versatility: The BNC female side utilizes the classic bayonet locking mechanism for rapid and secure attachment/detachment.

• Optimized RF Shielding: The solid brass construction provides a continuous ground path, ensuring excellent protection against EMI and RFI interference.

• Maximum Conductivity: High-purity gold plating on the center contact pin and socket ensures low contact resistance and superior corrosion resistance.

Key Features

• BNC Female to SMA Male Interface: Consists of a BNC Jack (with socket) and an SMA Plug (with pin and internal threads).

• Compact Streamlined Design: Ideal for portable test kits and high-density panels where space is a critical factor.

• Premium PTFE Dielectric: Offers high thermal stability and maintains consistent electrical performance across its frequency range.

• Industrial Durability: Rated for at least 500 mating cycles, ensuring long-term reliability in demanding professional environments.

• Broad Frequency Support: Reliable electrical performance for VHF, UHF, and lower microwave frequency applications.
