摘要

The emergence of increasing multifunctionality and high data rate advanced wireless standards, such as WiMAX and LTE-advanced, requires communication systems capable of operating at multiple frequencies simultaneously. This situation has led to scenarios where the radios with the ability to function at several distinct frequencies are required. Seamless transition from one existing standard (e.g., 3G) to upcoming standards (e.g., 4G) with backward compatibility is also a motivating factor for the deployment of multiband radio architectures. In principle, the design of multiband power amplifier (PA) is one of the most challenging aspects in any multiband radio considering the trade-off required in terms of efficiency and linearity.
