Layout and Power-S upply Bypassing
The MAX4112/MAX4113/MAX4117–MAX4120 have an
RF bandwidth and consequently require careful board
layout, including the possible use of constant-impedance
microstrip or stripline techniques.
To realize the full AC performance of these high-speed
amplifiers, pay careful attention to power-supply
bypassing and board layout. The PC board should
have at least two layers: a signal and power layer on
one side, and a large, low-impedance ground plane on
the other side. The ground plane should be as free of
voids as possible. With multilayer boards, locate the
ground plane on a layer that incorporates no signal or
power traces.
Regardless of whether a constant-impedance board is
used, observe the following guidelines when designing
the board. Wire-wrapped boards are much too induc-
tive, and breadboards are much too capacitive; neither
should be used. IC sockets increase parasitic capaci-
tance and inductance, and should not be used. In gen-
eral, surface-mount components give better high-
frequency performance than through-hole components.
They have shorter leads and lower parasitic reac-
tances. Keep lines as short and as straight as possible.
Do not make 90° turns; round all corners.
Observe high-frequency bypassing techniques to
maintain the amplifier’s accuracy. The bypass capaci-
tors should include a 1000pF ceramic capacitor
between each supply pin and the ground plane, locat-
ed as close to the package as possible. Next, place a
0.01μF to 0.1μF ceramic capacitor in parallel with each
1000pF capacitor, and as close to them as possible.
Then place a 10μF to 15μF low-ESR tantalum at the
point of entry (to the PC board) of the power-supply
pins. The power-supply trace should lead directly from
the tantalum capacitor to the V
CC
and V
EE
pins. To
minimize parasitic inductance, keep PC traces short
and use surface-mount components.
