Grounding, Bypassing,
and PC Board Layout
To obtain the MAX4137/MAX4138’s full 185MHz band-
width, Microstrip and Stripline techniques are recom-
mended in most cases. To ensure the PC board does
not degrade the amplifier’s performance, design the
board for a frequency greater than 1GHz. Even with
very short traces, use these techniques at critical
points, such as inputs and outputs. Whether you use a
constant-impedance board or not, observe the follow-
ing guidelines when designing the board:
Do not use wire-wrap boards. They are too inductive.
Do not use IC sockets. They increase parasitic
capacitance and inductance.
In general, surface-mount components have shorter
leads and lower parasitic reactance, giving better
high-frequency performance than through-hole com-
ponents.
The PC board should have at least two layers, with
one side a signal layer and the other a ground plane.
Keep signal lines as short and straight as possible.
Do not make 90° turns; round all corners.
The ground plane should be as free from voids as
possible.
