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 system module.
Signals with different frequencies take different paths, therefore being handled by different components.
