2.5 Performing Conducted Testing

As seen in Figure 2-9, the BP-CC3351 has an on-board SMA connector and component antenna. The SMA connector (J1) provides a way for testing conducted measurements. Alternately, a track pad for a U.FL connector (J2) is provided on-board to replace the SMA connector and provide a way to test in the lab using a compatible cable (see Figure 2-9).

A rework is needed before using the connector on J1/J2. This involves swapping the position of the existing 3.9pF capacitor to lead the transmission line on the desired connection (see Figure 2-9).

Note: For single band (2.4GHz) usage only, the user can swap the position of the two existing 10pF capacitors to bypass the diplexer. Additionally, the user must add a 50-ohm termination resistor (see Figure 2-10).
