PACKAGE#02A

Surface Wave Artifact from PCB

Revision(s) Affected:

Description:

Large PCBs area around the E-plane causes surface waves that create large ripples in the elevation direction of the AoP antenna radiation pattern.

Workaround(s):

Workaround #1:

GUID-9287BF49-300F-491E-9FE5-160DE6F59092-low.gif Figure 5-5 Small form factor board with PCB edge less than 0.3mm

Keep the Edge of PCB close to the edge of the AoP device in the E-plane to minimize the surface wave ripples.

or

Workaround #2:

If a larger board is needed for the solution, a trapezoid cutout with the PCB edge less than <0.3mm from the edge of the AoP should be implemented to minimize the ripples caused by surface waves.
