COMPONENT AND FUCTION FINISH

13. VCO IC (Voltage Control Oscilator)
the function as frequency oscillator/generator that be sent to pass Tx(Tranceiver) and frequency that enter to pass part Rx (Receiver) so that being equal with radiated. beside that, this component also functioned as pulse voltage regulator from RF signal processor.

14. RX/TX 
as enter/out signal

15. LCD 
this component will functioned to display all activities from handphones, as media communication reads and write in handphone. 

16. KEYPAD 
this component functioneds as device input that give data command to cpu then processed and sent to other component related to handphone

17. INFRA RED 
infra red a tool that transfer data or program. But in general infra red used to send and receive data from computer to handphone or conversely. Infra red will work when facilities activate good in handphone and or in computer. But usually when computer that used kind laptop or notebox so this facilities detect of system operation at installation. Actually function infra red this is same as does data cable, only data cable direct linked will into handphone while infra red is not such. this apparatus work by using light infra red distance between handphone one with other may not far apart, must face to face, and doesn't shut a certain. 

18. BLUETOOTH 
this tool is used to transfer data or functioned as mediator between a equipment with other equipment. Facilities bluetooth exist in handphone usually used to send or get data from computer, handphone other, or conversely has also and use this facilities. The bluetooth function in handphone in principle same like infra red. simply procedure from bluetooth use frequency stripe or radiowave, for delivery distance or data acceptance doesn't like infrared, bluetooth has overplus can be used to send and get data concurrently at the time of same. beside that bluetooth has also surplus can be used without having to close to one another between sender equipment with receivers equipment, in general distance can achieve hundreds meter.

19. BATTERY 
the function as electricity current source to give electricity current in mobile phone. battery for handphone there what kind, that is: Nickel-Metal Hydrate (nimh), Lithium-Ion(Lion), and Lithium-Poly-Mer (Lipoly).

Data and Audio Part

Data Part

Data Part functioneds as operating system that cultivate data and give command to entire parts found on part mobile phone. Data Part component consist of :

1. IC CPU
2. IC RAM
3. IC FLASH 
4. KEYPAD 
5. LCD 

Function CPU with support component is: 
1. IC CPU is data processing centre in handphone 
2. IC CPU work helped by IC RAM as saving operating system / program that walk in cellular telephone and IC FLASH that keep temporary data’s, and can be changed direct in mobile phone if user willing. 
3. while keypad here have functioned to command CPU to do data process appropriate handphone user willing 
4. LCD is getting command from CPU to displaying entire process that are walking in handphone. 
 
procedure every part : 
1. Data has been entered into to handphone has passed program that is on cable flash (to flasher) and data cable (to application) 
2. Data from computer that is PPM and MCU step into Ic Flash and Ic Flash keep data Ppm that consist of menu, application and language, this data kind temporary and convertible direct by user 
3. While data MCU sent to EEPROM (Elctrically Erase Programable Read Only Memory) that consist of handphone identity that is IMEI, sec. code and phone code 
4. CPU helped by IC RAM functioneds to processed data PPM exist in flash IC to sustained to ic hardware and displayed in screen (LCD) and check data in EEPROM as handphone identity to recognizable by CPU. 

Data Processing Diagram 
in newest cellular telephone set in this time there are some IC that is united to be one or integration, like: 
IC UEM/UAM 
this component has consisted of several components that integration, among others: 
Ic Power Supply 
Ic Audio 
Ic Charging 
Ic UPP 
this component has consisted of several components that integration, among others: 
1. IC CPU
2. IC EEPROM 
3. Ic Flash 

Audio Part 
that part in this component: 
Ic audio 
Loud speaker / ring tone poliponik 
Microphone 
1. Ic audio as voice signal vibration amplifiying sustained to loud speaker as voice signal vibration changer is voice vibration. 
2. Microphone will change voice vibration will be voice signal vibration that Amplified by Ic Audio. 
for telephone set kind selularl ringtone polyponik also cultivated by ic audio and sustained to loud speaker ringtone 
 
procedure every part: 
1. IC Audio gets voice signal from RF IC to Amplified and continued to loudspeaker 
2. In loudspeaker voice signal be be changed to be voice vibration so that audible. 
3. Microphone change voice vibration is voice signal and sustained to ic audio 
4. In voice ic signal audio is braced and amplified to RF IC to at transmit to pass part TX. 
5. Function CPU as controlling from work audio IC and regulate performance data IC formed audio. 
6. Voltage that step into IC audio that is Vbb as stanby voltage, Vcobba as voltage input moment to work it entire parts in audio ic and voltage vref as detector / voltage controlling into audio Ic.
