摘要
Abstract
Based on the polynomial model of TWTA( Traveling Wave Tube Amplifier) and ideal predistortion response curve,a novel diode-based predistortion Linearizer which consists of two non-linear branches was developed. The in-fluence of the diode parameters to predistortion response curve was discussed. Based on the analysis and simulation,a L-band practically predistortion cuicuit was designed and tested with the TWTA. The IM3 of TWTA with linearizer at Input Power Back Off(IPBO)of 3dB,6dB,9dB can separately be improved from -10.3 dBc,-14.3 dBc,-18 dBc to-12.1 dBc,-18.5 dBc,-26.9 dBc.关键词
