Johnson SMA Fixed Attenuators Connectivity for Business Critical Continuity SMA Fixed Attenuators Commercial Series Emerson Network Power Connectivity Solutions extends the Johnson line of products with the introduction of a range of SMA Fixed Commercial Attenuators. This range of attenuators is manufactured from non-inductive resistors making it an ideal choice for customers who need to precisely adjust signal levels, in applications that are under 2 watts. These attenuators are currently available in stock in 1, 2, 3,6 and 10 db, and available in other values on a made to order basis. Key Features & Benefits The important parameters associated with fixed attenuators include the level of attenuation, the flatness over a specified frequency range, VSWR, power-handling capability, package size, and performance over a given temperature range. The average power limit decreases linearly as temperature increases. Ideal for automated test applications The Johnson line of rugged stainless steel fixed attenuators offers industry leading quality and performance in addition to being competitively priced.
