_______________Detailed Description
The MAX4200–MAX4205 wide-band, open-loop buffers
feature high slew rates, high output current, low
2.1nV
√
Hz
voltage-noise density, and excellent capaci-
tive-load-driving capability. The MAX4200/MAX4203
are single/dual buffers with up to 660MHz bandwidth,
230MHz 0.1dB gain flatness, and a 4200V/μs slew rate.
The MAX4201/MAX4204 single/dual buffers with inte-
grated 50
output termination resistors, up to 780MHz
bandwidth, 280MHz gain flatness, and a 4200V/μs slew
rate, are ideally suited for driving high-speed signals
over 50
cables. The MAX4202/MAX4205 provide
bandwidths up to 720MHz, 230MHz gain flatness,
4200V/μs slew rate, and integrated 75
output termina-
tion resistors for driving 75
cables.
With an open-loop gain that is slightly less than +1V/V,
these devices do not have to be compensated with the
internal dominant pole (and its associated phase shift)
that is present in voltage-feedback devices. This fea-
ture allows the MAX4200–MAX4205 to achieve a nearly
constant group delay time of 405ps over their full fre-
quency range, making them well suited for a variety of
RF and IF signal-processing applications.
These buffers operate with ±5V supplies and consume
only 2.2mA of quiescent supply current per buffer while
providing up to ±90mA of output current drive capability.
__________Applications Information
Power Supplies
The MAX4200–MAX4205 operate with dual supplies
from ±4V to ±5.5V. Both V
CC
and V
EE
should be
bypassed to the ground plane with a 0.1μF capacitor
located as close to the device pin as possible.
Layout Techniques
Maxim recommends using microstrip and stripline tech-
niques to obtain full bandwidth. To ensure that the PC
board does not degrade the amplifier’s performance,
design it for a frequency greater than 6GHz. Pay care-
ful attention to inputs and outputs to avoid large para-
sitic capacitance. Whether or not you use a
constant-impedance board, observe the following
guidelines when designing the board:
Do not use wire-wrap boards, because they are too
inductive.
Do not use IC sockets, because they increase para-
sitic capacitance and inductance.
