2. IC Power Supply
3. Switch On / Off
4. CPU
1. When the phone is turned off, battery has given the current / voltage to the phone, namely to PA IC, IC regulators, charging IC, IC Interfaces
2. Power Supply IC process and dividing the current / voltage coming from the battery and then issue a standby voltage to the CPU
3. When Mobile In On it, the CPU gets the voltage Negative (-) of the Switch On / Off, then CPU Power Supply ordered to supply current / voltage to each section on the phone.
4. In recharging, the current / voltage of the Charger go through R Fuse that serves as a fuse / safety in case of excess flow into the IC Charging.
5. Current / voltage coming into the IC cahrging in though and issued as output should match the voltage at the battery.
6. On Charging Ic there as a controller shaped Charging Sense data associated with IC Power Supply, Function if there incompatibilities with Charging IC performance, the IC Power will decide replenishment by sending data to the IC CPU that charge failed. Known Not Charging / no fill.
7. Power Supply will issue a voltage (output) after the phone at On it, except the voltage VBB that serves as a standby voltage.
8. In the event of damage to the IC Power Supply, there will be no standby voltage / VBB of the Power Supply.
1.2. SIGNAL SECTION (rx AND TX)
Section siGNALPenerimaan (RX)
Parts or components that work to work on Cellular Telephone consists of several components, these components include:
1. Antenna
2. Antenna Switch
3. RX Filter (Filter)
4. Transistor (amplifier RX)
5. RF ICs
6. VCO
7. IC Power Supply
To determine whether or not the work part RX (Reception), it can be seen by looking at the Cellular Telephone on Netwaork selection settings, then select the menu option manually in the network.
How it Works Each Section Components:
1. Signals are captured / received by the antenna is routed to a terminal Antenna Switch
2. Antenna Switch will issue two RX signals (for Mobile Dual Band), the DCS-RX (1800MHz) and GSM-RX (900MHz), two signals are passed to filter the signal RX, RX signals are filtered and forwarded to the transistors as amplifier.
3. On the second transistor amplified RX signals to be transmitted to the filter to re-filtered and split the signal into 4 parts, namely the issue of two signals and two DCS-RX-RX GSM signals are forwarded to the RF IC
4. IC RF / IF Signal Processing RX and adjusted to the frequency established by the VCO
Signal transmitting section (TX)
Parts or components that work to work on Cellular Telephone consists of several components, these components include:
1. Antenna
2. Antenna Switch
3. TX filter (Filter)
4. IC PA
5. RF ICs
6. VCO
7. IC Power Supply
For detection work whether or not the TX (transmission), can be used lamp radiation / multitester.
How to do this are:
1. Turn on the phone with Sim Card (Card)
2. Make calls to 112 (emergency number)
3. Attach the lamp radiation / multitester near the antenna
4. For calibration Multitester put on AC 10V
5. If the lights on / needle multitester move, meaning TX work.
How it Works Each section:
1. VCO frequency form will be processed by the RF IC to form four output signals, ie two signals DCS and the two GSM-TX-TX to forward it to the filter in the TX (transmission)
2. VCO also serve as a Power Detector to regulate the voltage pulses of RF IC in sending data to the CPU.
3. In the fourth filter output signal that is sent by the RF IC in the form of a two-TX signal, namely DCS and GSM to be forwarded to the IC PA
4. In the second PA signal IC is amplified for transmission and then forwarded to the TX filter.
5. In the Filter Both signals are filtered and forwarded to the Antenna Switch
6. Antenna switch that serves as a terminal and combining both GSM and DCS signals to be transmitted via Antenna.
1. On the whole section is assisted by mobile phone signals at the amplifier IC Audio initial sound signal coming from the reception (RX) to be forwarded at the beginning of Loud Speakers and Amplifiers voice signal coming from the microphone to be forwarded goto the transmitting (TX) through IC RF / IF.
2. 26 Mhz crystal to function as plant signals to control signals on the RF IC is sent to IC Audio in the AFC (Automatic Frequency Control) as well as the voltage regulator in accordance with the needs associated components that are controlled by the CPU.
Part Data (Operating System)
Part of this data serves as the Operating System that manages data and is giving orders to all parts contained in the Cellular Telephone parts or components that work there are some parts, such as:
1. IC CPU
2. IC RAM
3. IC FLASH
4. Keypad
5. LCD
The tasks from the CPU itself as well as components that help
1. IC CPU is a data processing center on Cellular Telephone
2. IC CPU work supported by the IC RAM as a storage operating system / program running on a Cellular Telephone and Flash IC that stores data that is temporary, which can be changed according to user desires Cellular Telephone.
3. While the keypad function here ordered the CPU to process the data according to user desires Cellular Telephone
4. LCD received instructions from the CPU to display all running processes on Cellular Telephone.
How it Works Each section of the component itself:
1. Data is entered into through the Cellular Telephone Program that already exist in Computer intermediary Flash cable (for Flasher) and Data Cable (For apikasi)
2. Computer Data from the PPM and MCU into the IC Flash IC Flash and PPM data store consisting of Menu, applications and languages, the type of data is temporary and can be changed directly by users
3. While the MCU data is sent to the EEPROM (Elctrically Erase Programmable Read Only Memory), which consists of the Mobile Identity IMEI, Sec.Code and Phone Code
4. CPU assisted by IC RAM PPM data processing function is the IC Flash to be forwarded to the IC Hardware and displayed on the screen (LCD) and check the data in EEPROM as Cellular Telephone identity to be recognized by the CPU.
