Abstract
Various aspect of a system for a linearized transmitter including a power amplifier may include at least one transconductance amplifier that enables generation of a single analog quadrature signal. Transmitter mixers may enable generation of a plurality of upconverted RF signals in a corresponding plurality of RF processing chains based on the generated single analog quadrature signal. In various embodiments of the invention, a gain stage, for example gain stage, may also be referred to as an RF processing chain. Power amplifier circuit may enable generation of a corresponding plurality of RF output signals within a wireless communication system based on the generated plurality of upconverted RF signals.
