The Microlab/FXR AA series coaxial
attenuators are for general -
purpose applications in
the DC to 1 GHz frequency range. Either the
AB
series or AH series
is recommended for all
applications requiring greater accuracy or wider
frequency coverage.
The AA series attenuators are constructed of
resistive elements in a conventional π-type circuit
.
They are bi-directional, e
xceptionally rugged, and
negligibly affected by normal ambient
temperature and humidity changes.
AA series attenuators are available to
order
with special attenuation values, VSWR, power
ratings, connector series, and connector polarities
to meet your exact specifications. (7/98)
