STMicroelectronics, Catania, Italy Rapidly expanding market for multi-mode (MM) and multi-band (MB) cellular phones has recently fueled the demand for RF Power Amplifiers (PAs) that are able to operate with 2G, 2.5G and 3G standards. This trend minimizes component count, radio board size and cost while it increases power-added efficiency (PAE) needs in each operating mode as well as power level due to the probability distribution of the transmitted power [1]. The optimization of a PA for MM operation has resulted in innovative architectures exploiting the intrinsic high efficiency of a DC-DC converter, joined with the benefit offered by polar modulation applied to an RF PA
