Silicon-Germanium and Compound Semiconductor RF Front-Ends and Antennas
This community develops high-frequency integrated circuits and antenna systems for wireless communication, radar sensing, and millimeter-wave applications, utilizing silicon-germanium, gallium arsenide, and indium phosphide technologies.
The work centers on BiCMOS and HBT processes in SiGe, GaAs, and InP, focusing on power amplifiers, low-noise amplifiers, and phase shifters. Recurring design elements include phased arrays, MIMO antennas, bandpass filters, and frequency doublers operating in the GHz and terahertz ranges. Applications span 5G and 6G wireless networks, automotive FMCW radar, and satellite communications. The research emphasizes compact, fully integrated solutions for high-output power and wideband performance, with specific attention to D-band and millimeter-wave frequencies.
The largest share of the community's output is found in germanium research, accounting for 5.7% of all germanium research, and 2,619 papers here. Silicon contributes the highest paper count with 2,784 papers, representing 2.6% of silicon research.
The community comprises 7,095 papers, publishing primarily in IEEE Transactions on Microwave Theory and Techniques, IEEE Journal of Solid-State Circuits, and IEEE Transactions on Nuclear Science.
Recent work includes 6G phased-array beamformers, terahertz FMCW radar systems, and metamaterial-inspired MIMO antennas for future wireless networks.
