商品簡介
Wang recommends the envelope tracking approach in order to maximize the energy efficiency of a radio frequency power amplifier by keeping the power supply in compression over the whole modulation cycle, instead of just at the peaks, by dynamically adjusting the supply voltage to the amplifier. He describes the envelope tracking operation, signal generation and shaping, design, and implementation approaches as well as applications of the techniques in the context of radio frequency power amplifiers in wireless communications systems.
