ABSTRACT:
Power-efficient front-end topologies for radio frequency power amplifiers are described which may be used to implement full-duplex transceivers for wireless mobile terminals such as, for example, cellular phones. At least some of the described topologies employ highly efficient power amplifiers having well-optimized global feedback loops with noise-shaping capability.
