Compact Modelling and Experimental Power Amplifier Design and Characterization for 180 GHz Transmission (A06)

本项目主要针对带宽至少为30 GHz的180 GHz发射机的超高效率功率放大器（PA）和上转换器的实现和测量。这涉及到广泛的优化，特别是晶体管结构和动力电池布局，同时，通过精确的紧凑建模，包括物理效应，如击穿，热耦合，分布和电荷存储效应，影响毫米波频率下的效率和线性度。发射机的能量消耗旨在通过使其工作周期适应系统的占空比来进一步降低，因此需要研究在打开和关闭设备期间的瞬态沉降效应。

This project focuses mainly on the implementation and measurement of an ultra-high efficiency power amplifier (PA) and up-converter for a 180 GHz transmitter with at least 30 GHz bandwidth. This involves extensive optimization especially of the transistor structure and power-cell layout while, via accurate compact modeling, including physical effects such as breakdown, thermal coupling, distributed, and charge storage effects that impact efficiency and linearity at mm-wave frequencies. The energy consumption of the transmitter is aimed to be further reduced by adapting its operation period to the system’s duty cycle, thus requiring the investigation of transient settling effects during turning the device on and -off.
