SiGe and III-V Heterojunction Transistors for Millimeter-Wave Radar and 5G/6G Antennas
This community designs high-frequency integrated circuits and antenna systems using silicon-germanium and compound semiconductor technologies, primarily for automotive radar, wireless communication, and phased array applications.
The work centers on the design and characterization of SiGe BiCMOS and HBT transistors, with significant focus on power amplifiers, low-noise amplifiers, and phase shifters operating in the millimeter-wave and terahertz bands. Recurring applications include MIMO antennas, dipole arrays, and FMCW radar systems. The technical scope extends to GaAs pHEMTs and InP DHBTs, emphasizing wideband, broadband, and fully integrated circuit topologies. Specific components such as bandpass filters, frequency doublers, and compact antenna structures are developed to support high-gain, high-linearity signal processing. The research consistently targets the optimization of output power, phase noise, and frequency response within 130-nm and advanced CMOS processes, bridging the gap between discrete microwave components and monolithic integrated circuits for next-generation wireless standards.
The community is most heavily represented in Germanium research, accounting for 9.7% of all tracked Germanium papers, and Silicon research, comprising 2.2% of Silicon papers. In terms of absolute volume, Silicon contributes the most papers to this group with 8,473 entries, followed closely by Germanium with 7,715.
There are 15,905 papers in this community, published primarily in IEEE Transactions on Microwave Theory and Techniques, IEEE Journal of Solid-State Circuits, and Microwave and Optical Technology Letters.
Recent work includes the design of 8-channel phased-array receive beamformers for 6G FR3 systems, flat-gain power amplifiers in 130 nm SiGe BiCMOS technology, and machine-learning-based optimization of tunable high-gain terahertz MIMO antennas.
