IWTH5: System-level linearization and characterization of phased array transmitters for satellite communications

Presentation Abstract
Satellite communication systems are rapidly moving towards higher frequencies and larger signal bandwidths for increased capacity. These trends impose tight requirements on transmitter linearity and power amplifiers efficiency. This workshop introduces an overview of state-of-the-art phased array architectures and how they can be combined with linearization schemes for enhanced efficiency. Advanced measurements and characterization techniques will be combined with behavioral models and prototypes for accelerating the design, optimization, and testing of linearization techniques and beamforming algorithms. We are using practical hardware to demonstrate how to tradeoff design parameters and improve ACLR, EVM, and other metrics for different standard waveforms.
