Abstract
A switching mode RF power amplifier that employs a narrowband filter directly connected to the output, is presented. The efficiency improvement compared to a conventional class B PA and the influence of a transmission line between the PA and this filter is investigated. These techniques are illustrated by circuit simulation and verified by measurements. It is shown how the transmission line between the filter and the PA will influence both the efficiency and the distortion of the PA.
