RF and Millimeter-Wave Transceiver Chips Design

Dear Colleagues,

The rapid evolution of wireless communication systems, sensing technologies, and high-speed electronic platforms has driven continuous demand for radio-frequency (RF), millimeter-wave, and terahertz integrated circuits with higher output power, wider bandwidth, and improved system-level efficiency. These technologies play a critical role in a broad range of applications, including next-generation wireless communications, radar systems, satellite links, and emerging terahertz sensing and imaging systems. In particular, the GHz-to-THz frequency range poses unique challenges related to device limitations, circuit parasitics, power efficiency, and noise performance, especially when implemented using advanced III–V semiconductor technologies.

Recent progress in RF circuits, power amplifiers, filters, and beamforming architectures has enabled significant improvements in output power, array gain, and spectral efficiency. However, further advances are still required to address critical issues such as additive noise, nonlinear distortion, thermal constraints, and system-level integration. Moreover, the growing adoption of analog and hybrid beamforming techniques in large-scale antenna arrays introduces new design trade-offs across circuit, architecture, and system levels.

To address these challenges, it is essential to explore innovative circuit topologies, advanced III–V process technologies, and co-design methodologies that bridge devices, circuits, and wireless systems. In this context, this Special Issue aims to provide a comprehensive platform for presenting recent theoretical, technological, and experimental advances in RF, millimeter-wave, and terahertz electronics.

This Special Issue will cover, but is not limited to, RF and microwave circuits, high-power and high-efficiency power amplifiers, filters, terahertz integrated circuits, analog beamforming, and array architectures, as well as their applications in modern wireless communication systems.

The goal is to promote cross-disciplinary research and foster the development of high-performance electronic systems operating in the GHz and THz frequency ranges.
