Re: Urgent 5110 Hardware

[Florin Vancea]

AFAIK, the phone may draw a fairly big current from the power source while
transmitting. The maximum emission power is 2Watt but I've heard of peak
currents of up to 2 amps.
In a regular phone the battery itself plays the role of a buffer, providing
the energy for the current peaks.
If you do not want to put a battery in (and I suppose you don't) then you
must size properly your power source AND provide a LARGE capacitor after the
regulator, to cover the required current peaks.
If those are not there I suspect your phone is producing a bad signal and
the network is having trouble understanding it or the internal circuitry
simply do not have enough power to function properly.

HTH,
Florin

Hai  Every One

    I am doing some R&D on  Nokia 5110. Mobile Phone. The R&D is I am using
External Power Supply using LM350 and I 'm giving 4.1 V to the Phone PCB (
this is stripped of every thing Like LCD,KEYPAD and other non necessary
things.)
In 5110 there are two PCB I have removed the daughther PCB ( lcd,keypad)
USING Only the Main PCB I removed the main antenna I am using Single core
wire as antenna . Some times It is registering with the network some times
not


Some one can help me in this  Please

Thanks in Advance

Karthik
