_______________General Description
The MAX4106 evaluation kit (EV kit) simplifies evalua-
tion of the MAX4106 high-speed amplifier. The EV kit
circuit demonstrates the MAX4106 in the noninverting
configuration set to a gain of +5V/V. RF-style connec-
tors (SMA) and 75
terminating resistors are included
for video test equipment compatibility.
The EV kit comes with the MAX4106 installed. To evalu-
ate the MAX4107, simply order a free sample
(MAX4107ESA), replace the MAX4106 with the
MAX4107 on the EV board, and change the gain-
setting resistors for the desired gain. The minimum
closed-loop gain for the MAX4107 is +10V/V.

_________________________Quick Start
The MAX4106 EV kit is fully assembled and tested.
Follow these steps to verify board operation.
Do not
turn on the power supply until all connections are
completed.
1) The circuit requires supply voltages of 5V. Connect
these supplies to the corresponding pads marked
V+ and V-. Connect the power-supply ground to the
pad marked GND.
2) Verify that the J1 shunt is across pins 2 and 3 of the
3-pin jumper J1.
3) Apply a signal no greater than 0.64V
PK
(4.4dBm)
to the SMA connector marked IN.
4) Connect the output marked OUT to an oscilloscope
through a terminated 75
cable.
5) Turn on the power supply and verify the output sig-
nal on the oscilloscope.
Note: To evaluate the MAX4107, request a MAX4107ESA free
sample.

_______________Detailed Description
Voltage-Gain Adjustment
The MAX4106's gain can be adjusted with the following
minor modifications to the EV board:
1) Referring to Table 1, select the feedback (R
F
) and
gain-setting (R
G
) resistors with the desired gain.
2) Install R
F
and R
G
.
Layout Considerations
The MAX4106 EV kit layout has been optimized for
high-speed signals, with careful attention given to
grounding, power-supply bypassing, and signal-path
layout. The small, surface-mount, ceramic bypass
capacitors C2C5 have been placed as close to the
MAX4106 supply pins as possible. The unused pins
have been grounded to prevent unwanted noise from
coupling into the circuit.
Shutdown Control
The MAX4106/MAX4107 EV kit is a standard EV kit
used for many of Maxim's high-speed op amps. As a
result, a shutdown (SHDN) function is incorporated on
the EV kit, but does not apply to the MAX4106/
MAX4107. Because the shutdown control is not applic-
able to the MAX4106/MAX4107, verify that a shunt is
connected to pins 2 and 3 of jumper J1.
