Figure 3 shows the recommended device layout. The
ground pad vias have a diameter of 0.008 inches (0.20
mm) while the two external vias have a diameter of
0.010 inches (0.250mm). The internal vias are spaced
approximately evenly from the center of the pad. The
designer may choose to use more vias with a smaller
diameter (such as 0.005 inches or 0.125mm) since
changing the diameter of the via will result in little
change in inductance (i.e. the log function in Equation 2
in highly insensitive to parameter d) . Figure 4 shows a
typical insertion loss (S21) plot for the device using
Semtech’s filter evaluation board with 50 Ohm traces
and the recommended via configuration.
