4-9 Doherty増幅器対応DPDを用いた励振器の開発(第4部門 無線・光伝送)

抄録

Aiming towards low-power consumption transmitters for digital terrestrial television broadcasting, An exciter for the Doherty amplifier using DPD (Digital Pre-distortion) has been developed.. The exciter which can compensate distortion derived from the memory effect was achieved by adopting high precision DPD, suppressing to IM<-50dB.
