RX and TX Service Network Problems

RX and TX Service Network Problems:
here are some tips for RX and TX Service Network Problems

there is two
sections in network 1, Rx section. 2, Tx section. all technicians need
to use manual searching in mobile phone, testing for Rx section and Tx
section.

HOW TO FIND WHICH SECTION IS FAULT Tx (or) Rx?

Testing Rx section

use manual
for Testing Rx section, after searching Rx section good condition means
it shows network list like Airtel, hutch, (or) any other network list
in your area,

If Rx section bad condition after searching it shows NO NETWORK FOUND

1, after searching it shows network list means Rx section is ok.
2, after searching it shows NO NETWORK FOUND or some networks missing means Rx section is faulty.

Testing Tx section

Use manual
for testing Tx section, after searching it shows network list, then you
can choose your simcard network, if Tx section is good condition it
shows HOME NETWORK SELECTED, if Tx section is fault it shows NO ACCESS.


1, after selecting network it shows HOME NETWORK SELECTED means Tx section is ok.
2, after selected network it shows NO ACCESS means Tx section is fault.


Information of Rx section components and ics nokia dct-3 tech

1, antenna switch

2, RF IC ( Hagar ic )

3, AUDIO IC ( cobba ic)

4, crystal oscillator

5, filters

6, VCO (voltage control oscillator



Information of Tx section components and ics nokia dct-3 tech

1, PF IC (PA IC)


Information of Rx section components and ics nokia dct-4 tech

1, antenna switch

2, filters

3, RF IC

4, crystal oscillator

5, VCO (voltage control oscillator)

6, UEM IC


Information of Tx section components and ics nokia dct-4 tech


1, PF IC (PA IC)
