An Overview of State-of-the-Art D-Band Radar System Components

In this article, a literature study has been conducted including 398 radar circuit elements from 311 recent publications (mostly between 2010 and 2022) that have reported mainly in the F-, D- G-Band (80–200 GHz). This is intended to give state-of-the-art comparison on performance of different technologies—RFCMOS, SiGe/BiCMOS III–V semiconductor composites—regarding most crucial parameters Voltage-Controlled Oscillators (VCO), Power Amplifiers (PA), Phase Shifters (PS), Low-Noise (LNA) Mixers. The common topologies each element as well differences technolgies will futher be laid out while reasoning their benefits. Since not all devices were derived solely single device publications, necessary steps yield fairly possible taken. Results include area power efficiency RFCMOS, superior noise semiconductors continuous compromise SiGe. rarely published devices, being Mixers PSs, given frequency range also identified incentive for further developments.
