Method for receiving a radio frequency (RF) signal and RF receiver

A method for receiving radio frequency signals that appear as bursts, the method comprising the steps of:

• providing a local frequency signal with an oscillator,
• controlling the frequency of the oscillator with a phase locked loop,
• mixing the input signal with the local frequency signal for producing an intermediate frequency signal,
• demodulating the intermediate frequency signal for producing a data stream of the information,
• supplying power for the receiver means providing the method steps,
• turning off the supply power for supplying continuously power to the means providing the step of demodulation, and
• the step of turning off the supply power for a determined period of time from another receiver part provides another of said steps for receiving.

A receiver for receiving radio frequency signals which appear as bursts, the receiver comprising:

• an oscillator for producing a local frequency signal,
• a phase locked loop for controlling the frequency of the local frequency signal,
• a mixer for mixing the input signal with the local frequency signal for producing an intermediate frequency signal,
• a demodulator for producing a data stream of said information, and
• a power supply for supplying power for the receiver,
• means for keeping at least a part of the phase locked loop powered during a period between two consecutive bursts to be received, and
• a controller for turning off the supply power from the another receiver part for determined time during the period between two consecutive bursts to be received.
