演讲主题
面向卫星与合成孔径雷达应用的氮化镓射频前端芯片设计
GaN MMIC RF Front-End Design for Satellite and Synthetic Aperture Radar Applications
演讲内容简介
This talk discusses radio frequency (RF) front-end module (FEM) architectures for Synthetic Aperture Radar (SAR) in Earth observation applications and in satellite communications. It outlines the evolution of FEM architectures in response to recent advances in Gallium Nitride (GaN) Monolithic Microwave Integrated Circuit (MMIC) technology, which offers high power density, rapid switching, and superior thermal conductivity. These characteristics enable the development of high-efficiency, small form-factor power amplifiers, low-noise amplifiers resilient to overdrive, and linear high-power switches. It discusses the main challenges encountered when designing such FEMs and presents a step-by-step design methodology for fully integrated FEMs to achieve RF performance targets while meeting mechanical, thermal, and long-term reliability requirements, and ensuring suitability and scalability for large-scale phased-array transceivers in space applications.
