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.
