At low gains, G x RIN << RF. Therefore, the closed-loop
bandwidth is essentially independent of closed-loop
gain. Similarly, ZOL >> RF at low frequencies, so that:
Layout and Power-Supply 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 PCB 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
0.01F to 0.1F ceramic capacitor in parallel with each
1000pF capacitor, and as close to them as possible.
Then place a 10F to 15F low-ESR tantalum at the
point of entry (to the PCB) of the power-supply pins.
The power-supply trace should lead directly from the
tantalum capacitor to the VCC and VEE pins. To mini-
mize parasitic inductance, keep PC traces short and
use surface-mount components.
