Imoportant Hardware Component on Mobile Phone Device

Here is most hardware IC component that arranged on the mobile device.

IC Power Amplifier (PA)

This component acts as a voltage amplifier signal generated VCO (Voltage Controll oscillator). If your performance is not good component usually results borosnya battery, because PA requires considerable power to amplify the signal.

Antenna Switch / Duplexer

Switch that works automatically to determine the coupling antenna work as a duplexer that allows the two sub-systems of the receiving device or sending RF signals to work together through the same antenna as well as the separation between the high-frequency waves (DCS 1800 MHz) and low frequency (GSM 900 MHz) .

IC Filter

Serves as a filter RF signals pass frequency manner desired freq and reduce the other to go to the next section, both the incoming signal and the signal out.

IC IF Filter

A mixer circuit intermediatte Frequency function to change the frequency that comes out of the filter to obtain the difference in the frequency of the VCO frequency as a detector circuit audio encoder and decoder into the center frequency.

Signal Processor (RF IC)

Has the most defining work to cultivate employment entry and exit signals simultaneously separating radio signals and sound waves. Components that generate pulses of 26Mhz, which is then processed by the RF Processor which then produces pulses at 13MHz for the pulse to the system logic on the CPU, to the course of the baseband digital systems, especially the CPU.
Voltage Control Oscillator (VCO)

There are two kinds of VCO for the receiver and the transmitter signal. Acting as a deterrent (maker) first signal when the CPU starts commanding Mobile to transmit or receive. Served divide VCO waves generated by X-TAL is worth 26 MHz and half divided kenilai at 13 Mhz and return it to the RF IC to be processed into a wave of RX (Reiceiver) in the scale of 900 Mhz and 1800 Mhz (for dual-band) and 1900 MHz plus (for tri band).

Power Supply IC (UEM)

The part that governs the distribution voltage electrical current to different components obtained from the Battery to be set according to the needs of each of the components in question.

Audio IC (COBBA)

Functioning as material processing RX signal wave (Reiceiver) and transmits the X-Tal to be converted to an audio wave wave wave alphanumeric alphanumeric or change to a digital audio waveform so that the voice sounded clear with the help of loudspeakers (speakers).

Charging IC

Components that serve as controller charging of mobile battery charging transformer into.

Switch On / off

Manually serves as a connector and disconnect an electric current charges. (The switch to turn on and turn off cell phones)
User Interface (UI)

Tool or medium that serves as a terminal that regulates the work of other components such as LED lights / ringing and vibrating. This component is always there to control the driver UI system components are ordered from the CPU.

Central processing unit (CPU)

The main processors used in devices that can receive information. Serves as executor of the IC and IC Flash RAM that automatically compare, modify, reduce. Multiply - divide and unite all the information a matter of logic output - input by mobile users and transmitted to the LCD as a form of results that can be seen and read.
Random Access Memory (RAM)

Tool to store temporary data memory (memory volitale), where the data will be lost if it is not electrified (power). to change and setting  usually manually entered by the users of mobile phones, such as ringtones, logos, names and addresses.
Eraseable Electrically Programmable Read only memory (Eeprom)

The instrument contains the basic program for phone operation performed by the CPU that has been programmed by the factory itself and Articles can not be changed by the user's mobile phone, except for specific programming languages ​​and tools.The data stored in the EEPROM are:
- No. IMEI (International Mobile Equipment Identifier)
- Security Code
- ESN (Electronic Serial Number)
- MIN (Mobile Identification Code)
- SID (System Identification Code)

Flash IC

IC FLASH has a function as a data storage that is permanent memory of the Articles, which such data will not be lost even if the power of the phone is turned off. Flash IC contains important data such as the MCU and PPM, the data contains data MCU Operating System (OS), while the PPM Data contains data such as display Langue pack, Ringtones, etc.. In addition there is also a MCU and PPM CP (Content Pack) and a user area that stores the data contained on the features like Mobile Applications, Games, Wallpapper, Video, Phone Book, etc.. Any changes or additions melukan memory must use the computer / software.

Infra Red Diode (IR diode)

IR diode transmit / Receive, two diodes as infra-red transmitter and receiver instead of cables connecting software. function to send and receive waves that contain specific data without having to use cables.
Light Emited Diode (LED) tools that can emit light when an electric current was given.
Flexible Cable

The tool contains a thin sheet-shaped piece of copper that can conduct electric current as the liaison section with one another as well as elastic.
Buzzer / Ringer

Tool that makes noises / sounds as ringtones / alert.
SIM Reader

Interface with mobile phone cards.
Plug In

Tools that can connect the device charging battery (Charger) to the PCB.
Board connector

These components typically found on some specific type of mobile phone. In general, the phone that has this device is mobile phones that have two board (PCB) and the function of the device is to connect the two boards.
