摘要： Examples disclosed herein relate to a dynamic supply modulation power amplifier architecture for millimeter wave applications. The architecture includes phase shifters coupled to a power input port, power amplifiers coupled to respective power output ports, variable gain amplifiers coupled to the phase shifters and to the power amplifiers and are configured to supply dynamically varying input power to the power amplifiers. The architecture includes a first look-up table coupled to the variable gain amplifiers to control the variable gain amplifiers. The architecture also includes a second look-up table coupled to the power amplifiers, where each of the power amplifiers is supply modulated by active drain voltage modulation controlled by the second look-up table and variable input power from the variable gain amplifiers. Other examples disclosed herein include a radar system for use in an autonomous driving vehicle and an analog beamforming antenna for millimeter wave applications.

摘要： Examples disclosed herein relate to an intelligent metamaterial radar. The radar has an Intelligent Metamaterial (“iMTM”) antenna module to radiate a transmission signal with a dynamically controllable iMTM antenna in a plurality of directions based on a controlled reactance and generate radar data capturing a surrounding environment. The radar also has an iMTM interface module to detect and identify a target in the surrounding environment from the radar data and to control the iMTM antenna module.
