A design methodology for a power amplifier (PA) with harmonic control is based on the simplified real frequency technique (SRFT). This is validated with a compact broadband power amplifier that has a maximum output power of 42.8 dBm and an efficiency of 55 to 70 percent in the 1.7 to 3 GHz band. With a 100 MHz LTE-A signal, linearization is accomplished using digital predistortion (DPD). With DPD linearization, -47.01-48.5, -47.01-47.7 and -47.61-46.4 clBc ACLR are measured at 1.95, 2.15 and 2.55 GHz respectively at an average output power of 33 dBm. [ABSTRACT FROM AUTHOR]
