Abstract

This paper presents a new approach for realizing the output network of class-S power amplifiers in the 900MHz band. The idea is to use bond-wires instead of lumped inductors thus improving Q factor and broadband impedance termination at the output of the switching stage. A filter made of bond-wires and planar capacitor was designed and fabricated. Measurements were also performed in a class-S PA module and compared to the convention. Measurements of the proposed network were performed and compared with filter solution using SMD elements.
