A reflective TWTA predistortion linearizer for Ka-band application

摘要：

　　A predistortion linearizer used for Ka-band travelling wave tube amplifiers (TWTAs) was proposed.Based on analysis of nonlinear transfer characteristics of TWTA using a power series,the inverse nonlinear distortion characteristics of predistorter which was also the model of predistortion linearizer was proposed.A reflective structure was used to realize the linearizer,its composed of anti-parallel schottky diodes,quadrature hybrid,matching networks seen from the diodes.The Carrier-to-Intermodulation(C/I) of Kaband TWTA was improved a maximum of 19dB by proposed predistortion linearizer.
