distance from the IC to these resistors, thus reducing
the capacitance associated with longer lead lengths.
SMA connectors were used for best high-frequency
performance. Because distances are extremely short,
performance is unaffected by the fact that inputs and
outputs do not match a 50Ω line. However, in applica-
tions that require lead lengths greater than 1/4 of the
wavelength of the highest frequency of interest,
constant-impedance traces should be used.
Fully assembled evaluation boards are available for the
MAX4104 in an 8-pin SO package.
