This I.C. controls audio frequency, and sound is produced.

12. Module with Universal Energy (UEM IC)

It has several functions as a power supply, charger, audio processor, ringer, and vibrator.

13. Antenna Switch

This device receives, transmits, and switches frequencies like GSM, D.C.S., and P.C.S.

14. IF IC

This I.C. is also known as Hager IC, Molner IC, and RF IC. It functions as an amplifier, mixing, and demodulator.

15. Ear Speaker

Mobile phones are equipped with an ear speaker attached to the top. During incoming calls, you can listen to the sound.

16. Microphone

During transmission, it converts voice signals into electrical signals or tone signals. An audio I.C. receives this signal.

17. The L.E.D. (light-emitting diode) is a type of light source.

Light is produced on the keyboard and displayed by this component.

18. RF Crystal

Any mobile phone is not complete without this crystal. Phones use crystals with frequencies ranging from 13 MHz to 36.4 MHz. If the crystal fails, the Phone becomes unusable.

19. Socket for SIM cards

Using the SIM card stick, also the SIM card is held in place and can be read or written to.

20. Memory Card

An external memory card is a storage device for storing photos, videos, audio, etc. As well as the external memory cards include S.D. cards, Mini SD cards, and Micro SD cards.

21. Vibrator Motor

It provides vibrating alerts when incoming calls or messages are received when you are in silent mode or have the option turned on.

22. SIM card

Subscriber Identity Module is also known as SIM. The GSM mobile phone uses this technology. The card contains a microchip that stores all information and data related to the USER. An unlocked GSM phone is of no use without a SIM Card.

23. P.F.O.

As an amplifier or bandpass filter, it is found in network sections near the antenna switch. The filter and amplifier amplify also the frequency of the network.

An erroneous PCO will result in

  • There is no mobile network
  • Network problems on mobile devices
  • Your mobile phone may be dead due to a P.F.O. short-circuit
  • The trouble with other networks

24. Antenna socket for external antennas

Accessories can be attached to this socket to allow external antennas to be connected. An increased range of the internal antennas is achieved with this.


This module performs several essential functions.


This module performs several other functions.

27. OMAP Module

Applications software is processed, and U.I. software is controlled.

28. Connector with hands-free functionality

Utilizing a Headset or Earphone, you can keep in touch without touching the Phone.

29. Flash I.C.

Programs are stored in this memory, and non-volatile data is stored in this memory.

30. R.A.P. 3G IC

With this I.C., SD-RAM memory modules and non-Flash memory modules were combined in the modem section. Also, the cellular protocol used by Rap3G works with GSM and WCDMA.

31. USB Connector
