Concurrent dual band 2.4/3.5GHz fully integrated power amplifier in 0.13µm CMOS technology

This paper proposes novel dual-band matching network, suitable for the design of integrated concurrent dual band power amplifier in a multi-standard radiofrequency frontend. The effectiveness of the proposed dual band matching network was demonstrated through the implementation of a power amplifier operating at 2.4 GHz and 3.5 GHz in IBM 0.13 mum CMOS technology. The designed 1.25 mm times 1.25 mm dual band PA allowed for Power Added Efficiency (PAE) and output power of about 42% and more than 18 dbm, respectively, at both frequencies.
