发明名称 APPARATUS AND METHOD FOR RADIO COMMUNICATION
摘要 The present invention relates to a radio communication unit (20) comprising radio communication means (23, 25, 27) for communication (reception and/or transmission) in one or more frequency ranges with associated channel spacings. The radio communication means use oscillator signals for channel selection in the frequency ranges. The radio communication unit further comprises a system clock (77) generating a clock signal having a predetermined frequency that is not divisible by all the channel spacings. According to the invention the oscillator signals used in the channel selection are generated by a frequency synthesizer circuit (29) in the form of a fractional-N PLL circuit, said clock signal being fed as a reference frequency signal to the fractional-N PLL circuit. The invention also comprises a radio telephones comprising such a radio communication unit and the use of such a radio communication unit.
