PCB Layout
A suggested PCB pad print for the miniature, Minipak
1412 package used by the ATF-551M4 is shown in
Figure 39.
This pad print provides allowance for package
placement by automated assembly equipment without
adding excessive parasitics that could impair the high
frequency performance of the ATF-551M4. The layout is
shown with a footprint of the ATF-551M4 superimposed
on the PCB pads for reference.
