LAYOUT CONSIDERATIONS
As is the case with all high speed amplifiers, careful attention to
printed circuit board layout details prevent 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 from the area near the input signal lines reduces
stray capacitance. Chip capacitors should be used for supply
bypassing. One end of the capacitor should be connected to the
ground plane, and the other should be connected no more than
1/8 inch away from each supply pin. An additional large
(0.47 μF to 10 μF) tantalum capacitor should be connected in
parallel, although not necessarily as close, in order to supply
current for fast, large signal changes at the AD8022 output.
Signal lines connecting the feedback and gain resistors should
be as short as possible, minimizing the inductance and stray
capacitance associated with these traces. Locate termination
resistors and loads as close as possible to the input(s) and
output, respectively. Adhere to stripline design techniques for
long signal traces (greater than about 1 inch). Following these
generic guidelines improves the performance of the AD8022 in
all applications.
