PROBE MATRIX BOARD

The probe matrix board uses the same stackup as the evaluation

board, but a different layout designed to perform measurements

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

eliminates the mismatch reflections caused by connectors,

cables, and board layout. Therefore, the probe matrix board

provides more accurate measurement of the device performance

than the evaluation board. Figure 29 shows the top view of the

probe matrix board layout.

The probe matrix board includes a through reflect line (TRL)

calibration kit allowing board loss de-embedding. The actual

board duplicates the same layout in matrix form to assemble

multiple devices at one time. All s parameters were measured

on this board.
