IC FLASH FUNGTION
IC Flash is used to data storage permanently, the data will not lost when power is died. The data are MCU data and PPM data.MCU data contents Operating System (OS) data. while data on interface, language packaged, ringtone dll. Data which saved on IC Flash not only Operating System data, but also Content Pack data and User Area which saved fiture of mpbile phone
likes : Game, Application, Wallpaper, Ring Tones, Picture, Film, Phonebook.
IC PA
IC PA are the first component which conducted if damage detected on transmitter shares (TX). Because IC PA only there are in transmitter band (TX) and hold big responsible on the band damaged. IC PA fungtion to give the power of signal transmit when calling. IC PA transmit bad radiasi for health.
MOBILE PHONE CAN'T READ SIMCARD
Usually this problem is signed with appear this word "INSERT YOUR CARD atau INSERT SIM CARD" on screen of mobile phone. if your mobile phone's language is Indonesian, so the word will be "MASUKKAN KARTU SIM".
This problem is caused Sim Card connector doesn't work well. Try it, released the sim card dan the battery. Clean the connector use clean towel for losing waste which adheres or crust. Show off the sim card in exact position. if not success, its mean there are broken off transmission. The latest solution is change sim card connection.
if the sim card hasnot read, it's mean the sim card has worn-out. its happens cause of the sim card often taken part (change).
BATTERY INDICATOR ISN'T SHOWN
Mobile phone only hold out during 5 minute, and then restart.its happen firm and tight. This problem maybe caused of complication on mobile phone software. The first solution is upgrade firmware with flashing. So, there isnot problem of your battery.
RF FUNGTIONS
RF prosesor or system PLL are signal processor (frequency trick). Tricking signal frequency divided on 2 process, there are :
- Modulation (mixing) data/audio signal and bring sinal. On transmitter, data signal will be modulation with bring signal which processed by RF / IF, in order to data/audio signal can be send to operator.
- Demodulation (signal separation of data / voice signal with the carrier). At the receiver (recipient), the signal received by mobile phone from the service is still mixed with the carrier signal. For the carrier signal must be separated from the signal data / voice that can be processed by the audio IC to be processed, and forwarded to the speaker.
