The invention relates generally to a method and an arrangement for
receiving a radio frequency (RF) signal and an RF receiver. Particularly
the invention relates to controlling and reducing power consumption in a
radio receiver. The invention can advantageously be applied in receiving
arrangements of radio systems, wherein information is transferred in
bursts, such as a receiver of Digital Video Broadcasting (DVB) system.
According to the invention, during the time between two bursts the power
supply is maintained in at least in some parts of the phase locked loop
PLL, while one or several other parts of the receiver are turned off for
a certain time period between the two bursts. The present invention
enables fast tuner lock-in time and still offers a considerable saving in
total power consumption of the receiver.
