active modulator

The high efficiency digital audio amplifier technology [2]is adopted to develop the power supply modulator and the Class-D switching amplifier technology[3] is adopted to develop the high efficiency RF amplifier.

本論文利用EER( Envelope Elimination and Restoration)線性功放技術的基本原理[1]，采用數字音頻功放技術[2]實現高效率電源調制器，采用Class-D開關放大技術[3]實現高效率載頻放大器，開發了一個集AM調制和放大于一體的高效率線性功率放大器。
