BOARD LAYOUT
As is the case with all high speed applications, careful attention
to printed circuit board (PCB) layout details prevents associated
board parasitics from becoming problematic. Proper RF design
technique is mandatory. The PCB should have a ground plane
covering all unused portions of the component side of the
board to provide a low impedance return path. Removing the
ground plane on all layers from the area near the input and
output pins reduces stray capacitance, particularly in the area of
the inverting inputs. Signal lines connecting the feedback and
gain resistors should be as short as possible to minimize the
inductance and stray capacitance associated with these traces.
Termination resistors and loads should be located as close as
possible to their respective inputs and outputs. Input and
output traces should be kept as far apart as possible to minimize
coupling (crosstalk) though the board. Wherever there are
complementary signals, a symmetrical layout should be provided
to the extent possible to maximize balanced performance.
When running differential signals over a long distance, the
traces on the PCB should be close. Doing this reduces the
radiated energy and makes the circuit less susceptible to RF
interference. Adherence to stripline design techniques for long
signal traces (greater than about 1 inch) is recommended.

POWER SUPPLY BYPASSING
The ADA4311-1 operates on supplies from 6 V to 12 V. The
ADA4311-1 circuit should be powered with a well-regulated
power supply. Careful attention must be paid to decoupling the
power supply. High quality capacitors with low equivalent series
resistance (ESR), such as multilayer ceramic capacitors (MLCCs),
should be used to minimize supply voltage ripple and power
dissipation. In addition, 0.1 μF MLCC decoupling capacitors
should be located no more than -inch away from each of the
power supply pins. A large, usually tantalum, 10 μF capacitor is
required to provide good decoupling for lower frequency signals
and to supply current for fast, large signal changes at the
ADA4311-1 outputs. Bypassing capacitors should be laid out
in such a manner as to keep return currents away from the
inputs of the amplifiers, which minimizes any voltage drops that
can develop due to ground currents flowing through the ground
plane. A large ground plane also provides a low impedance path
for the return currents.
