Applications information
A typical circuit application is shown in Figure 1. This is suitable for 75
transmission line
connections at both the input and the output and is useful for distribution of wide-band signals
such as video via cables. The 75
reverse terminating resistor R4 gives the correct matching
condition to a terminated video cable. The amplifier load is then 150
in parallel with the local
feedback network.

The wide bandwidth of this device necessitates some care in the layout of the printed circuit. A
continuous ground plane is required under the device and its signal connection paths, to provide
the shortest possible ground return paths for signals and power supply filtering. A double-sided
or multi-layer PCB construction is required, with plated-through via holes providing closely
spaced low-inductance connections from some components to the continuous ground plane.
For the power supply filtering, low inductance surface mount capacitors are normally required. It
has been found that very good RF decoupling is provided on each supply using a 1000pF NPO
size 0805 or smaller ceramic surface mount capacitor, closest to the device pin, with an adjacent
0.1 F X7R capacitor. Other configurations are possible and it may be found that a single 0.01 F
X7R capacitor on each supply gives good results. However this should be supported by larger
decoupling capacitors elsewhere on the printed circuit board. Values of 1 to 10 F are
recommended, particularly where the voltage regulators are located more than a few inches from
the device. These larger capacitors are recommended to be solid tantalum electrolytic or ceramic
types.
Note particularly that the inverting input of this current feedback type of amplifier is sensitive to
small amounts of capacitance to ground which occur as part of the practical circuit board layout.
This capacitance affects bandwidth, frequency response peaking and pulse overshoot. Therefore
to minimize this capacitance, the feedback components R2 and R3 of Figure 1 should be
positioned as close as possible to the inverting input connection.
