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.
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.
KE231 .... designed for low-gain applications
(Av = ±1 to ±5)
KE220 .... high bandwidth (-3dB BW of 190MHz),
lower output current (50mA)
KE200 .... general purpose (-3dB BW of 95MHz)
KE103 .... high output current (200mA)
The KE104 is an encased version of the KH104AI, a DC
to 1.1GHz linear amplifier with a fixed gain of 14dB and
50Ω input and output impedances. These features, coupled
with excellent distortion and VSWR characteristics,
make the KE104 ideal for applications in wideband
analog and high-speed digital communications,
radar, and fiber optics transmitters and receivers.
KE104 .... DC to 1.1GHz, fixed 14dB gain, low distortion.
Ordering Information
KE104
Since gain and input and output impedances are fixed
on the KE104, simply designate the connector type
required by: KE104-BNC or KE104-SMA.
KE103, KE200, KE220, and KE231
Due to the flexibility possible with these amplifiers,
the user must specify several parameters when ordering:
The full part number is KEnnn-p-con-Zi-Zo-Av,
nnn: specify 103, 200, 220, or 231
p: specify N (non-inverting) or I (inverting)
con: specify BNC or SMA connectors or NDC for no case
Zi: specify input impedance in ohms
Zo: specify output impedance in ohms
Av: specify voltage gain with output unterminated
(ie: Zload = ∞) (see example)
Select Zi, Zo, and Av within the following constraints:
Parameter KE103
Av ±1/±40
max Zin

1500
Av
non-inverting 10k
min Zout

Example:
KE200-N-BNC-75-50-20 means a KE200 with a non-inverting
gain, BNC connectors, 75W input impedance, 50W output
impedance, and a voltage gain of 20V/V (unterminated
output). (When driving a realistic load, the actual gain is
reduced by the factor Zload/(Zload + Zo) due to the resistive
divider action of the output impedance, Zo, and the load
connected to the amplifier, Zload. The unterminated voltage
gain, Av, should be selected with this in mind.)
