ADF5002 EVALUATION BOARD PCB
The evaluation board has four connectors as shown in Figure 8.
PCB MATERIAL STACK-UP
The RF input connector (J4) is a high frequency precision SMA The evaluation board is built using Rogers RO4003C material connector from Emerson. This connector is mechanically (0.008 inch). RF track widths are 0.015 inch to achieve a controlled compatible with SMA, 3.5 mm, and 2.92 mm cables. 50 Ω characteristic impedance. The complete PCB stack-up is shown in Figure 9.

Evaluation Board PCB Layer Stack-Up unused output should be correctly terminated using a 50 Ω SMA termination. The chip enable (CE) pin can be controlled using the T1 test point. If this function is not required, the test point can be left unconnected.
