APPARATUS FOR UP-CONVERTING MULTICHANNEL DIGITAL RADIO FREQUENCY

摘要

The present invention relates to a multi-channel digital radio frequency up-conversion device . More particularly, the present invention is to modulate the digital signal sent by the channel to the RF (radio frequency) signal , is related to multi-channel digital radio frequency up-conversion device for the digital signal up to a frequency of the channel of the broadband RF signal will . Multi-channel digital radio frequency up according to an embodiment of the present invention is a conversion device , each receiving a plurality of digital signal received plurality of digital modulator for performing the digital modulation ; And is characterized in that by receiving the digital signal from each of a plurality of digital frequency modulator comprises a DAC for converting the broadband RF signal are different from each other . ;
