Emerson Network Power, a business of Emerson and a leader in enabling Business-Critical Continuity™, announces the Johnson product line 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 under 2 W. These attenuators are currently available in stock in 1, 2, 3, 6 and 10 dB, and are available in other values on a made-to-order basis.

The important parameters associated with these fixed restriction of hazardous substances (RoHS) compliant attenuators include the level of attenuation, the flatness over a specified frequency range, voltage standing wave ratio (VSWR), power-handling capability, package size and performance over a given temperature range. The average power limit decreases linearly as temperature increases.
