General Description
The KE Series amplifiers are designed to take full
advantage of Fairchilds 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
50input 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:

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.)

2. When the amplifier is configured with an output impedance (Zout > 0, the maximum output
voltage swing (at the load) is reduced by the factor Zload/(Zload + Zout). See the example on page 1.
3.
These amplifiers must be kept out of saturation; in other words, the output voltage
(determined by Vin and Av.) must be kept away from the supply voltage.

4. In the non-inverting configuration, the input voltage to the KE103 must not exceed ±5V.
Discussion
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. Gain
At the nominal gain setting of +20 (+2 for the KE231),the amplifiers will
typically provide 100% of the specified bandwidth; higher gains will
reduce the bandwidth somewhat as shown in the graph.
Relative Bandwidth vs. Load
Listed under the typical specifications table are the nominal loads at
which the amplifiers will typically provide 100% of the specified band-
width. Heavier loads decrease the bandwidth as the plot indicates. (The
total load on the amplifier is the sum of the output impedance, Zo, and
the load connected external to the amplifier, Zload).
Relative Bandwidth vs. VCC
All of the KE Series amplifiers are designed to operate on ±15V
supplies. The user may elect, however, to use lower supplies but at
some sacrifice in performance as shown in the plot.
