The research of rf linear power amplifier in ofdm system 系统的射频功率放大器线性化的研究
Feedforward linear power amplifier design for cdma2000 1x system 系统正向前馈线性功率放大器设计
( 2 ) made a research in the composing mode of the high - frequency linear power amplifier of uhf complete solid - state transmitter ( 2 )对uhf全固态电视发射机高频线性功率放大器的组成方式进行了研究。
Most of the power amplifiers using in the military systems today are importations and the army needs the homemade linear power amplifiers urgently 目前,相关军用设备所用高功率线性功放基本上为国外进口,受国外制约严重,迫切需要解决其国产化问题。
We combined the predistortion and feed - forward technologies and added self - reaction control module to build a linear power amplifier system . and it has high efficiency and high linearization 本自适应预失真、前馈控制系统将射频和自动控制有机结合,达到了高效率、高线性度的目的。
