featuring an amplifier and input/output attenuators integrated
into a single package. A wide selection of amplifiers and
customized input/output attenuators provide flexibility
in setting gain and input/output levels. For convenience,
our most popular amplifiers are offered as standard options

of the part number and the components will be selected
to give optimum performance at that frequency. For example,
more gain might be realized with some loss in broadband
flatness.
