Linearization of an RF power amplifier using a combined FIR-IIR amplifier model

摘要

Linearization of an RF power amplifier using a combined FIR-IIR amplifier model A highly non-linear RF amplifier exhibiting significant memory effects may be modelled with less use of FPGA and ASIC circuitry by using a combined FIR and IIR arrangement. The combined IIR-FIR technique requires fewer coefficients than a pure FIR technique. The RF amplifier may be a multi-stage amplifier of Doherty configuration. The modelling technique may be applied to other non-linear devices or processes.
