Abstract

This paper introduces a broadband outphasing power amplifier (OPA) meticulously designed for operation within the 3.0~3.7 GHz frequency range, strategically addressing the imperative for wideband and high peak-to-average-power ratio (PAPR) signal transmission in the realm of 5G wireless communications. The proposed OPA employs the current combining mode in its architectural framework, intricately integrating a multi-stage bandpass network to formulate the combiner. In order to substantiate the viability of the proposed design, a prototypical broadband model is meticulously constructed. Experimental results unequivocally demonstrate that the maximum output power is confined within the ambit demarcated by points 44.78dBm to 45.03dBm. Furthermore, saturation and 6 dB power back-off drain efficiencies are meticulously delineated within the intervals 63.4% to 72.6% and 51.6% to 76.4% respectively at 3.0~3.7 GHz. These empirical findings unequivocally affirm the efficacy of the designed broadband OPA in adeptly meeting the stipulated requisites for 5G wireless communications.
