HS-1100RH
Radiation Hardened, Ultra High Speed
Current Feedback Amplifier
The HS-1100RH is a radiation hardened high speed,
wideband, fast settling current feedback amplifier. Built with
Intersil’s proprietary, complementary bipolar UHF-1 (DI
bonded wafer) process, it is the fastest monolithic amplifier
available from any semiconductor manufacturer. These
devices are QML approved and are processed and screened
in full compliance with MIL-PRF-38535.
The HS-1100RH’s wide bandwidth, fast settling characteristic,
and low output impedance make this amplifier ideal for driving
f ast A/D conv erters.
Component and composite video systems will also benefit
from this amplifier’s performance, as indicated by the
excellent gain flatness, and 0.03%/0.05 Deg. Differential
Gain/Phase specifications (RL = 75).
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-94676. A “hot-link” is provided
on our homepage for downloading.

Typical Applications
Optimum Feedback Resistor
The enclosed plots of inverting and non-inverting frequency
response illustrate the performance of the HS-1100RH in
various gains. Although the bandwidth dependency on
closed loop gain isn’t as severe as that of a voltage
feedback amplifier, there can be an appreciable decrease
in bandwidth at higher gains. This decrease may be
minimized by taking advantage of the current feedback
amplifier’s unique relationship between bandwidth and RF.
All current feedback amplifiers require a feedback resistor,
even for unity gain applications, and RF, in conjunction with
the internal compensation capacitor, sets the dominant
pole of the frequency response. Thus, the amplifier’s
bandwidth is inversely proportional to RF. The HS-1100RH
design is optimized for a 510 RF at a gain of +1.
Decreasing RF in a unity gain application decreases
stability, resulting in excessive peaking and overshoot. At
higher gains the amplifier is more stable, so RF can be
decreased in a trade-off of stability for bandwidth.
The table below lists recommended RF values for various
gains, and the expected bandwidth.
PC Board Layout
The frequency response of this amplifier depends greatly on
the amount of care taken in designing the PC board. The
use of low inductance components such as chip
resistors and chip capacitors is strongly recommended,
while a solid ground plane is a must!
Attention should be given to decoupling the power supplies.
A large value (10µF) tantalum in parallel with a small value
(0.1µF) chip capacitor works well in most cases.
Terminated microstrip signal lines are recommended at the
input and output of the device. Capacitance directly on the
output must be minimized, or isolated as discussed in the
next section.
Care must also be taken to minimize the capacitance to
ground seen by the amplifier’s inverting input (-IN). The
larger this capacitance, the worse the gain peaking, resulting
in pulse overshoot and possible instability. To this end, it is
recommended that the ground plane be removed under
traces connected to -IN, and connections to -IN should be
kept as short as possible.
An example of a good high frequency layout is the
Evaluation Board shown in Figure 2.
Driving Capacitive Loads
Capacitive loads, such as an A/D input, or an improperly
terminated transmission line will degrade the amplifier’s
phase margin resulting in frequency response peaking and
possible oscillations. In most cases, the oscillation can be
avoided by placing a resistor (RS) in series with the output
prior to the capacitance.
Figure 1 details starting points for the selection of this
resistor. The points on the curve indicate the RS and CL
combinations for the optimum bandwidth, stability, and
settling time, but experimental fine tuning is recommended.
Picking a point above or to the right of the curve yields an
overdamped response, while points below or left of the curve
indicate areas of underdamped performance.
RS and CL form a low pass network at the output, thus
limiting system bandwidth well below the amplifier bandwidth
of 850MHz. By decreasing RS as CL increases (as
illustrated in the curves), the maximum bandwidth is
obtained without sacrificing stability. Even so, bandwidth
does decrease as you move to the right along the curve. For
example, at AV= +1, RS = 50, CL = 30pF, the overall
bandwidth is limited to 300MHz, and bandwidth drops to
100MHz at AV = +1, RS=5, CL = 340pF.
Evaluation Board
The performance of the HS-1100RH may be evaluated using
the HFA11XXEVAL Evaluation Board.
