  • Abstract
    Summary form only given, as follows. This paper presents a systematic methodology to design a diode-based RF predistorter that can linearize power amplifiers with dual inflection points in their distortion characteristics. The proposed structure contains an anti-parallel configuration of Schottky diodes, with a PIN diode in parallel, connected to a hybrid using λ/4 transmission lines. The proposed linearizer when applied to a commercial power amplifier shows IM3 cancellation of 10 dB in 1 MHz separation between tones at 2.14 GHz.
