EVALUATION BOARD PCB
The evaluation board has four connectors as shown in Figure 8.
The RF input connector (J4) is a high frequency precision SMA
connector from Emerson. This connector is mechanically
compatible with SMA, 3.5 mm, and 2.92 mm cables.

Figure 8. Evaluation Board Silkscreen—Top View
The evaluation board is powered from a single 3.0 V to 3.6 V
supply, which should be connected to the J1 SMA connector.
The power supply can also be connected using the T3 (VDDx)
and T2 (GND) test points.
The differential RF outputs are brought out on the J2 and J3
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.
PCB MATERIAL STACK-UP
The evaluation board is built using Rogers RO4003C material
(0.008 inch). RF track widths are 0.015 inch to achieve a controlled
50 Ω characteristic impedance. The complete PCB stack-up is
shown in Figure 9.
