ABSTRACT:
The invention relates to a device for digital-to-radio frequency conversion, the device comprising: conversion cell matrices for digital-to-radio frequency conversion; means for providing a digital data signal; means for dividing the digital data signal into data signal groups; means for generating clock signals, the clock signals having different phases, the number of clock signals being the same as the number of data signal groups; means for synchronizing the data signal groups by using the clock signals; means for conveying the synchronized data signal groups to the conversion cell matrices, the number of conversion cell matrices being the same as the number of data signal groups; and means for synchronizing each conversion cell matrix by using the clock signal with which the synchronized data signal group conveyed thereto was synchronized for generating interpolation values.
