Average current reduction in (W)CDMA power amplifiers

Average current reduction in (W)CDMA power amplifiers

Statistical average current consumption of conventional CDMA and WCDMA [(W)CDMA] power amplifiers is compared to that obtained by using DC-DC converters, analog bias control, and low power efficiency enhancement (LPEE) techniques. A discussion of theoretical limits, strengths, and weaknesses for eac...

Zusammenfassung:Statistical average current consumption of conventional CDMA and WCDMA [(W)CDMA] power amplifiers is compared to that obtained by using DC-DC converters, analog bias control, and low power efficiency enhancement (LPEE) techniques. A discussion of theoretical limits, strengths, and weaknesses for each approach is presented
