传统的功率回退应用方法存在器件及效率方面的限制。
However, traditional power back off method owns poor efficiency and is limited by electronic devices.
功率回退分为上行功率回退(upbo)和下行功率回退(DPBO)。
Power back-off to VDSL2 is divided into upstream power back-off (UPBO) and downstream power back-off (DPBO).
目前线性功率放大器的设计主要采用前馈、预失真和功率回退等线性化技术。
Feedforward, Predistortion and Feedback linearization techniques are mostly used in Linearity Power Amplifier Design.
所设计的射频2W线性功率放大器是基于负载线匹配原理，采用功率回退法技术。
The 2W linear RF Power Amplifier in this paper is designed in Feedback method, based on Loadline Theory.
虽然通过功率回退，可以得到较好的线性度，但是对于峰均比高的信号而言，效率就会很低。
If we simply back-off the input signal to achieve the linearity required for the power amplifier, the power amplifier efficiency will be very low for high PAR signals.
