Abstract
To avoid any dead time when switching between different frequency bands it is proposed to set a programmable multiband frequency synthesizer unit (12) adapted to generate an output signal in at least two frequency bands into a sleep mode before switching to a new frequency band, then to program the programmable multiband frequency synthesizer unit (12) according to the new frequency band, and finally to activate the programmable multiband frequency synthesizer unit (12) for operation in the new frequency band.
