Pushing the Envelope of RF/mm-Wave Power Generation by Relearning Ohm’s Law
Spectrum efficient modulations with high peak-to-average-power ratios (PAPR) are widely employed in many high-performance wireless communication systems from low-GHz software-defined radios to 5G mm-Wave links. This growing trend has posed stringent requirements on next-generation power amplifier (PA) designs and transmitter architectures. Going beyond more conventional PA design paradigms that mostly focus on peak output power and peak efficiency, next-generation RF/mm-Wave PAs should achieve both power efficiency and linearity in the entire power back-off region (PBO) to amplify the large-PAPR signals with high efficiency and fidelity. Moreover, it is increasingly important to explore PA carrier frequency reconfiguration and support large modulation bandwidth that will enable future multi-functional transmitters.
This seminar talk will present several new RF and mm-Wave PA architectures and their silicon-implementations recently developed at Georgia Tech Electronics and Micro-System (GEMS) lab. In addition, I will demonstrate a multi-feed antenna concept that achieves direct low-loss on-antenna power combining of multiple mm-Wave PAs for high-power long-range mm-Wave communications.
