| Abstract(in English) | When direct modulation scheme is applied for a digital radio transmitter to miniaturize a terminal, it often causes degradation of the error vector magnitude (E.V.M.) of modulation signals by coupling the transmitted signal with the PLL synthesizer output. This paper describes its mechanism and solution for improvement. |
