GAIN ADJUSTMENT AND INTERFACING
The effective gain of the ADL5565 can be reduced using a number
of techniques. A matched attenuator network can reduce the
effective gain; however, this requires the addition of a separate
component that can be prohibitive in size and cost. Instead, a
simple voltage divider can be implemented using the combination
of additional series resistors at the amplifier input and the input
impedance of the ADL5565, as shown in Figure 36. A pair of
resistors is used to match to the impedance of the previous stage.

Figure 36. Gain Adjustment Using a Series Resistor
Figure 36 shows a typical implementation of the divider concept
that effectively reduces the gain by adding attenuation at the
input. For frequencies less than 100 MHz, the input impedance
of the ADL5565 can be modeled as a real 66 , 100 , or 200
resistance (differential) for maximum, middle, and minimum
gains, respectively. Assuming that the frequency is low enough
to ignore the shunt reactance of the input and high enough so
that the reactance of moderately sized ac coupling capacitors
can be considered negligible, the insertion loss, Il, due to the
shunt divider can be expressed as

The insertion loss and the resultant power gain for multiple
shunt resistor values are summarized in Table 10. The source
resistance and input impedance need careful attention when
using Equation 3, Equation 4, and Equation 5. The reactance
of the input impedance of the ADL5565 and the ac coupling
capacitors must be considered before assuming that they make
a negligible contribution.
