KE Series  
Encased Amplifiers  
Features  
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.  
Wide bandwidth, fast settling, high slew rate  
Low distortion and overshoot  
Linear phase  
Easy to use encased form  
Direct replacement for E103, E104, E200,  
E220, and E231  
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.

communication systems

The KE±04 is an encased version of the KH±04AI, a DC  
to ±.±GHz linear amplifier with a fixed gain of ±4dB and  
ꢀ0input 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.

Ordering Information  
KE104  
Select Z , Z , and A within the following constraints:  
i
o
v
Since gain and input and output impedances are fixed  
on the KE±04, simply designate the connector type  
required by: KE±04-BNC or KE±04-SMA.

Z : specify input impedance in ohms  
KE200-N-BNC-7ꢀ-ꢀ0-20 means a KE200 with a non-inverting  
gain, BNC connectors, 7ꢀW input impedance, ꢀ0W output  
impedance, and a voltage gain of 20V/V (unterminated
