g.
C969 Pin1(
DC
)
: Check whether power detector (U956) is good or not.
The main function of power detector is to sense RF signal by means of
converting RF to DC voltage. The voltage level on C969 Pin1 shall be 1.3V ~
1.5V as maximum output power, approximate 23.5 dBm, is emitted. Power
detector needs to be reworked if no voltage level is measured in the situation of
maximum output power.
h.
C955
: Check whether PA (U953) operates normally or not. PA needs to
be reworked if DC-DC converter supplies DC voltage to PA and power is
measured within -63dBm~-55dBm on C955. The following figure is an
example of C955 signal measurement on the spectrum analyzer.
i.
L851 Pin1(
DC
)
: Check whether DC-DC converter (U951) is good or not.
The voltage level on L851 Pin1 shall be 2.7V ~ 2.9V as RF power is emitted.
DC-DC converter needs to be reworked if no DC voltage is measured on L851
Pin1.
j. The next process returns to calibration and pretest after the defect
component is found out and reworked.
