Outphasing Power Amplifier Design Investigations for 2.5G and 3G Standards

This paper presents investigations on outphasing power amplifier realizations based on a 2-stage 0.35 mum SiGe-bipolar PA design for 850 MHz and 1800 MHz. A Chireix combiner, a 90deg hybrid coupler and a Wilkinson power combiner were designed and all types were characterized in terms of efficiency and linearity for the usage in mobile phone applications.
