Abstract

The invention relates to an amplifying system (100) for amplifying a communication signal, the amplifying system (100) comprising a processor (101 ) being configured to compare magnitudes of the communication signal with a predetermined threshold, and to decompose the communication signal into a lower portion communication signal and an upper portion communication signal upon the basis of the predetermined threshold, wherein the lower portion communication signal indicates magnitudes of the communication signal below the predetermined threshold, and wherein the upper portion communication signal indicates magnitudes of the communication signal above the predetermined threshold, a Doherty amplifier (103) comprising a primary amplifier (105), a secondary amplifier (107), and a further secondary amplifier (109), the Doherty amplifier (103) being configured to amplify a first amplifier signal derived from the lower portion communication signal to obtain an amplified lower portion communication signal, an auxiliary amplifier (111) being configured to amplify a second amplifier signal derived from the upper portion communication signal to obtain an amplified upper portion communication signal, and a combiner (113) being configured to combine the amplified lower portion communication signal with the amplified upper portion communication signal to obtain an amplified communication signal.

Description

technical field [0001] The invention relates to the field of communication signal amplification. Background technique [0002] Modern wireless communication networks are increasingly designed to provide high data rates and sophisticated data processing capabilities to mobile devices within the wireless communication network. Recent approaches to increasing data rates and increasing data processing capabilities are based on employing communication signals with increased peak-to-average power ratio (PAR) and / or increased operating bandwidth. [0003] To amplify communication signals, different types of amplifiers can be used. For example, a Doherty amplifier can be used to amplify communication signals, wherein the Doherty amplifier can be regarded as an improved class B amplifier. However, current types of amplifiers may suffer from reduced efficiency when amplifying communication signals having a high peak-to-average power ratio (PAR) and / or a high operating bandwidth.
