The power level of three - order intermodulation is tested . the mathematics model is validated . the way in technics is given to reduce the power level of three - order intermodulation 从多个角度研究无源交调,建立交调的数学模型,测量了天线的三阶交调功率电平,对数学模型进行验证,并提出降低交调的工艺方法。
An overview of the intermodulation distortion analysis of cmos gilbert mixers is presented . the main difficulties in performing the nonlinearity analysis in mixers are discussed in detail 本文给出了当前文献中对cmosgilbert型混频器互调失真分析的概述,并对分析混频器非线性性能中所遇到的主要困难进行了详细讨论。
The simulation results show the cubic predistorting linearization system can achieve 46db third - order intermodulation distortion ( imd3 ) suppression . 2 . the indexing method of lut predistorting linearization system is studied in this dissertation 仿真研究表明由该三阶扰动器组成的模拟预失真系统能有效抑制的imd2分量,并可达到46db的三阶交调( imd3 )压缩性能。
Since the envelope of modulated signal fluctuates , these methods generate unwanted intermodulation distortion ( imd ) products in a nonlinear radio frequency ( rf ) power amplifier ( pa ) . so it is necessary to use linearization technique to reduce the adjacent channel interference ( aci ) 但包络变化的调制信号经过非线性射频功放后会产生交调分量,因此必须采用线性化技术来减少由此产生的邻道干扰。
In communication systems like this , on account of nonlinearity which may arouse intermodulation of power amplifier may bringing the increaseing of ber because interferes from adjacent channel . hence , we did the analysis of relationship between im3 and ber in the system 但是在正是因为采取这种调制方式,由于功率放大器的( pa )非线性失真会引起交调效应产生同频及邻频信道的干扰而使误比特率( ber )增加。
