RF description

Receiver (RX)

An analogue signal is received by the phone's antenna. The signal is converted to a digital signal and is then

transferred further to the baseband (eg. to the earpiece).
The receiver functions are implemented in the RF ASIC.
Signals with different frequencies take different paths, therefore being handled by different components.

The principle of GSM and WCDMA is the same.
