Troubleshooting
The phone receives the RF signal
from the Antenna or the RF test
port, the received RF signal is
routed through the Diplexer –
FL11 to mono block duplex SAW
filter-FL12. The RF signal is then
routed to the Front End IC (FE
IC) – U100, which contains LNA
which provides a 10-12 db gain to
the received RF signal, and U100
provides inter stage filtering and it
contains Mixer which down
converts the frequency.
