RF SECTION The RF section is the part of the cell-phone circuit is also known as RF Transceiver. It is the section that transmit and receive certain frequency to a network and synchronize to other phone. The RF - A radio section is based on two main Circuits. 1 Transmitter / TX 2 Reciever / RX A simple mobile phone uses these two circuits to correspond to an other mobile phone. A Transmitter is a circuit or device which is used to transmit radio signals in the air. Reciever is simply like radios which are used to recieve transmissions(Radiation) which is spread in the air by any transmitter on a specific frequency. POWER MANAGEMENT A power management section in mobile phones is designed to handle energy matters that is consumed in mobile phones. There are two main sub sections in a single power section ANALOG BASEBAND VOICEBAND CODEC This section converts andprocess the analog to digital (A/D) signals and digital to analog signals (D/A).

CPUCPU( Centeral Processing Unit) The Central Processing Unit
(CPU) is responsible for interpreting and executing most of the
commands from the users interface. It is often called the "brains"
of the microprocessor, central processor, "the brains of
thecomputer"
CHARGING SECTIONThe Charging section is based on a charging IC
which takes power from an external source and gives it to battery
to make it again power up when it is exhausted. this section uses
convertibly 6.4 V from an external battery charger and regulates it
to 5.8V wile giving it to battery.BATTERYUse as a source of
power
