Power efficiencies of linear transmitter architectures for handportable, satellite communications

The provision of a linear transmit section within a mobile transceiver facilitates the use of arbitrarily amplitude-and-phase modulated signalling, potentially resulting in flexible and spectrally efficient communication. This paper highlights some relevant narrowband, linear transmitter architectures appropriate to satellite handportable and mobile transceivers, and attempts to quantify their relative merits in terms of power efficiency and complexity
