Abstract
Embodiments are directed to systems, apparatuses and methods for providing self-consistent outphasing signal separation. In one scenario, such an apparatus includes the following: a receiver configured to receive a variable-envelope signal and an outphasing separator including a digital electronic component configured to split the received variable-envelope signal into first and second constant-envelope signals. Splitting the received variable-envelope signal includes implementing various trigonometric or other functions using a consistent phase. The apparatus further includes a first analog component chain that includes various analog electrical components configured to receive and process the first constant-envelope signal, as well as a second analog component chain that includes various analog electrical components configured to receive and process the second constant-envelope signal. The apparatus also includes an analog combiner configured to combine the first and second constant-envelope signals for transmission to other entities or systems.
