KE Series
Encased Amplifiers
Features
General Description
The KE Series amplifiers are designed to take full
advantage of Fairchild’s high-performance DC-
coupled operational amplifiers in an easy-to-use,
encased form. This format makes the KE Series
amplifiers an excellent choice for use on the bench,
in a test station, or in other environments needing
both high performance and ease of use.

Applications
The op amp-based KE Series amplifiers provide a
wide selection of features as well as the ability to
customize parameters such as voltage gain and out-
put impedance to the application.
ꢀ
For use on the bench or in a test station as a video
amp, pulse amp, line driver, etc.

The KE±04 is an encased version of the KH±04AI, a DC
to ±.±GHz linear amplifier with a fixed gain of ±4dB and
ꢀ0Ω input and output impedances. These features, coupled
with excellent distortion and VSWR characteristics,
make the KE±04 ideal for applications in wideband
analog and high-speed digital communications,
radar, and fiber optics transmitters and receivers.

Discussion
KE2ꢀꢀ
The performance specified above is that typically seen for a
nominally-configured KE Series amplifier; performance for different
configurations can be determined using the graphs. Other parameters
not shown can be approximated by referring to the individual hybrid
data sheets.

Relative Bandwidth vs. Load
At the nominal gain setting of +2ꢀ (+2 for the KE23±),the amplifiers will
typically provide ±ꢀꢀ% of the specified bandwidth; higher gains will
reduce the bandwidth somewhat as shown in the graph.
