Abstract

A wideband power amplifier includes a set of amplifiers connected in parallel to amplify signals from input ports of the amplifiers, a matching network configured to match the signals amplified by the amplifiers with predetermined load values, the matching network having a first impedance frequency response as a monotonically decreasing function of frequency of the amplified signals in a target operation frequency range, a converter network configured to convert the signals matched by the matching network, and an impedance flattening network having a second impedance frequency response as a monotonically increasing function of frequency of the amplified signals in the target operation frequency range.
