General Description
The KH104 linear amplifier represents a significant
advance in linear amplifiers. Proprietary design
techniques have yielded an amplifier with 14dB of
gain and a -3dB bandwidth of DC to 1100MHz. Gain
flatness to 750MHz of ±0.4dB coupled with excellent
VSWR and phase linearity gives outstanding pulse
fidelity and low signal distortion.
Designed for 50Ω systems, the KH104 is very easy to
use, requiring only properly bypassed power supplies
for operation. This translates to time and cost savings
in all stages of design and production.
Fast rise time, low overshoot and linear phase make
the KH104 ideal for high speed pulse amplification.
These properties plus low distortion combine to
produce an amplifier well suited to many communi-
cations applications. With a 1.1GHz bandwidth, the
KH104 can handle the fastest digital traffic, even
when the demodulation scheme or the digital coding
format requires that DC be maintained. It is also
ideal for traditional video amplifier applications such
as radar or wideband analog communications systems.
These same characteristics make the KH104 an excellent
choice for use in fiber optics systems, on either the
transmitting or receiving end of the fiber. The low
group delay distortion insures that pulse integrity
will be maintained. As a photomultiplier tube pre-
amp, its fast response and quick overload recovery
provide for superior system performance.
The KH104 is constructed using thin film resistor/
bipolar transistor technology, and is available in the
following versions:
KH104AI
-25°C to +85°C
14-pin double-wide DIP

... V in Capacitance if µF If lower offset and offset drift are required, a low frequency op amp may be used in conjunction with the KH104 in a composite configuration. The suggested circuit appears in Figure 2. Its method of operation is to compare an attenuated version of the output signal to the input signal and apply a correcting voltage at the offset adjust pin.
