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 (240), while one or several other parts (202, 204, 224, 225, 230, 262, 270) 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.
