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

ADRF5020 at close proximity to the 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.
