摘要

研究功率晶体管射频放大器带外校正元件实现的两种变体(借助基本物理可实现的无源电路和借助有源滤波器)的带外校正互调失真的效率。结果表明，通过无源电路进行校正，可以得到IMD/sub /降低的分数，最高可达10…13 dB，而通过有源滤波器的校正允许获得评分高达25 dB。

On applications of active filters for reduction of nonlinear distortions

Study efficiency of out-of-band correction of intermodulation distortions for power transistor RF amplifiers for the two variants of realization of out-of-band correction elements (with help of elementary physically realizable passive circuits and with help of active filters). It is shown that the correction by means of passive circuits allow to get scoring on reduction of IMD/sub 3/ up to 10...13 dB, whereas the correction by means of active filters allow to get scoring up to 25 dB.
