In this paper, the wideband and dual-band architectures for digital predistorters (DPD) are compared in terms of the DPD models used, hardware implementations, complexity and linearization performance. The advantages and disadvantages of each architecture are outlined and hardware measurements are performed using an amplifier prototype to illustrate the differences between the two approaches.
In this paper, a hardware-software system is proposed for the wideband characterization and linearization of power amplifiers exhibiting memory effects. The designed prototype includes a signal generation and a feedback paths for applications in the 1GHz to 2.5GHz frequency band and supports instantaneous bandwidths of up to 60MHz. The hardware platform is coupled with a software interface that implements...
