It is capable of bi-directional operation up to 50 GHz and is thus perfectly suited for 64 Gbps data signals. The attenuation values can be set by our easy to use software SHF SCC or by any self-programmed script for automated measurements. 1 dB within a 22 dB dynamic range. Engineers working in RF and high-speed communication test and measurement have the need to fine adjust signal levels to fit exactly the requirements. Up to now, adjusting the. Bird's 5 Watt RF Attenuators offer a dependable step up in power handling for RF professionals who demand both performance and durability. Designed with robust convection cooling and full shielding, these attenuators reduce signal levels safely while preventing stray radiation—keeping your systems. These precision attenuators feature positive mechanical stops between steps and offer the industry's widest attenuation range (0 to 99 dB), with frequency coverage through 18 GHz (Ku band) to provide broadband capability for RF applications. This type of component is generally used to balance signal levels in the signal chain, to extend the dynamic range of a system, to provide impedance matching, and to. A directional attenuator functions in one direction only.
