Abstract

This disclosure is directed to a power amplifier (PA) including circuitry to amplify and filter transmission signals in a radio frequency (RF) circuit. The PA may include multiple core amplifiers coupled to a power combiner to amplify and filter the transmission signals. For example, the PA may activate the core amplifiers to provide the transmission signals with a peak output power. Alternatively, the PA may activate a reduced number of the core amplifiers to provide the transmission signals with a reduced output power lower than the peak output power. Activating a portion of the PA when providing the transmission signals with a reduced output power may reduce a power consumption and improve power efficiency of the PA.
