Data Sheet ADF5000 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 control ed compatible with SMA, 3.5 mm, and 2.92 mm cables. 50 Ω characteristic impedance. The complete printed circuit board (PCB) stack-up is shown in Figure 9.

09129- The differential RF outputs are brought out on the J2 and J3 Figure 9. Evaluation Board PCB Layer Stack-Up SMA connectors. If only one of the outputs is being used, the 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.
