DEVICE FOR INPUTTING THE SIGNAL OF A DIGITAL-RF CONVERTER CAPABLE OF PREVENTING THE DISTORTION OF AN OUTPUT SIGNAL

摘要

PURPOSE: A device for inputting the signal of a digital-RF converter is provided to improve a signal-noise ratio by generating noise generated by the excessive response of an input signal in a specific frequency or a random frequency.;CONSTITUTION: A device for inputting the signal of a digital-RF converter(100) includes a phase-modulated signal input unit inputting a phase-modulated transmission signal into the LO switch(130) of the digital-RF converter; and a digital signal input unit modifying a digital signal in order to correspond to the phase-modulated transmission signal and inputting the modified digital signal into the data switch(121,122) of the digital-RF converter.;COPYRIGHT KIPO 2013
