Abstract
A wireless communication device (UST), comprising an input for receiving baseband data (I, Q) in a first signal having a first frequency. The device also comprises circuitry () for increasing the first frequency, to form a second signal having a second frequency, in response to a first frequency reference signal (IF), and the device comprises circuitry () for increasing the second frequency, to form a third signal having a third frequency, in response to a second frequency reference signal (LO). Lastly, the device comprises an antenna (ATU) for transmitting the baseband data at a final transmission frequency selected as a band within a predetermined set of frequency bands. With reference to the preceding, the first frequency reference signal and the second frequency reference signal are variable and are selected in response to the final transmission frequency which is a particular band selected as a different band at different times and from the predetermined set of frequency bands.
