PROBE MATRIX BOARD

Figure 22 and Figure 23 show the top and cross sectional views

of the probe matrix board that measures the s-parameters of the

ADRF5021 at close proximity to RF pins using the GSG probes.

The actual board duplicates the same layout in matrix form to

assemble multiple devices and uses RF traces for through,

reflect, and line (TRL) calibration.
