Pro Signal SMA Attenuator 3dB 50 Ohm DC-6GHz - Nickel Brass
Precision 3dB SMA coaxial attenuator for RF applications up to 6GHz. 50 Ohm, 1W average power, nickel-plated brass. For comms, test, aerospace.
The Pro Signal SMA Attenuator is a precision 3dB coaxial attenuator designed for critical signal management in high-frequency applications up to 6GHz. Engineered for superior RF performance, it provides accurate signal attenuation while maintaining excellent impedance matching and minimal signal distortion. Its robust construction ensures reliable operation across a wide range of demanding environments.
Featuring a nickel-plated brass body for enhanced durability and shielding, this attenuator utilises high-quality gold over nickel plated beryllium copper and brass centre contacts. These materials ensure excellent conductivity, corrosion resistance, and long-term connection integrity. The PTFE insulation and hermetically sealed design guarantee stable electrical characteristics and protection against environmental factors.
The design incorporates thick film resistor technology and sub-miniature coaxial connectors (SMA) with a screw-on coupling mechanism, providing a secure, low-loss connection suitable for repeated mating cycles. This makes it an ideal choice for applications where signal fidelity and connector reliability are paramount.
Key Applications
This versatile component is essential in communications and networking infrastructure, test and measurement setups, and high-reliability sectors such as aerospace, defence, and military electronics. It is perfectly suited for use in RF systems, signal generators, spectrum analysers, and any circuit requiring precise power level adjustment or impedance matching.
