Solution
2.7 Performing Conducted Testing
The BoosterPack board by default ships with the RF signal connected to the onboard chip antenna.
Figure 11 shows the miniature UMC connector (Murata MM8030-2610) on the RF path of the board, which
can be used to measure the performance in a conducted mode. In addition to the Murata connector, the
board contains a U.FL connector (see
Figure 12 ) that can be used to conduct testing, or connect an
external antenna. An onboard U.FL (Murata) connector provides a way to perform testing in the lab using
a compatible cable. Alternately, for testing the conducted measurement an U.FL connector is provided on
the board. The use of this connector requires a rework to be performed, which involves swapping the
position of a resistor, as shown in
Figure 11 and Figure 12 .
