PROBE MATRIX BOARD

The probe matrix board uses same stackup as the evaluation

board but a different layout designed to take measurements

using ground, signal, ground (GSG) probes at close proximity

to the RFx 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.
