APPLICATIONS INFORMATION
EVALUATION BOARD PCB
Use RF circuit design techniques for the PCB used in the
application. Ensure that signal lines have 50 Ω impedance when
the package ground leads are connected directly to the ground
plane (see Figure 14. Use a sufficient number of via holes to
connect the top and bottom ground planes.
The evaluation board has two connectors, as shown in Figure 14.
The RF input connector (J1) and the RF output connector (J2)
are PCB mount SMA connectors.
The evaluation board is powered from a single 3 V supply;
connect this supply using the J3 (VCC) and J4 (GND) test points.
See Figure 13 and Table 5 for the evaluation board schematic
and the bill of materials, respectively.
