In this paper, an approach to high efficiency power amplifier performance over a wide frequency range is discussed. Results for practical implementation of a multiband and multi-mode handset power amplifier are shown. Measurements demonstrate feasibility of the concept for WCDMA, DCS1800 and PCS1900 high-efficient operation. A PAE of better than 38% at 27 dBm output power and an ACLR of -37 dBc in WCDMA operation, as well as greater than 50% PAE at 30 dBm output power in the DCS1800 and PCS1900 band are documented.
