Connectivity for Johnson Business Critical Continuity SMA Fixed Attenuators SMA Fixed Attenuators Commercial Series Key Features & Benefits Emerson Network Power Connectivity Solutions extends the Johnson line of products with the introduction of a range of SMA connectors per MIL-STD-348A SMA Fixed Commercial Attenuators. This range of attenuators Rugged Stainless Steel Construction is manufactured from non-inductive resistors making it an ideal Hex body for torque wrench choice for customers who need to precisely adjust signal levels, in tightening 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 Excellent VSWR and Flatness values on a made to order basis. Compact design Ideal for automated test applications 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. The Johnson line of rugged stainless steel fixed attenuators offers industry leading quality and performance in addition to being competitively priced.
