Linearization of the 5G Power Amplifier below 6 GHz by DPD Compensation Technique

The linearization of single stage broadband power amplifier at 3.5 GHz by using DPD Compensation technique is presented in this paper. Linearization effects with one iteration (direct) method are analysed in simulation for 20 MHz LTE signal and for 50 MHz 5G signals (FBMC and FOFDM) for various power levels of output signal. Moreover, the linearization is performed with two iterations for LTE and 5G FBMC, UFMC and FOFDM signals.
