RF tuning after repairs
Following tunings have to be performed after repairs:
• Repairs in the TX part will require "TX Power Level Tuning".
• When component replacements around the modulator area (RF path from UEM
via RF ASIC to RF PA) have been done, "TX IQ Tuning" is additionally required.
• In general, repairs in the RX front-end always require "RX Calibration" and “Rx
Band Filter Calibration” for
all three bands
.
• Repairs in the PLL circuit always require "RX Calibration" of the low band
(GSM900).
• If the RF ASIC was replaced all calibrations mentioned above have to be carried
out.
