Abstract
This session covers advanced integrated passive devices operating at frequencies ranging from several-GHz to 300GHz. Specifically, it highlights the development of a fully differential, ultra-compact broadband rat-race coupler using folded-inverted coupled lines in 180nm CMOS, and an ultra-wideband, low-loss, and high-isolation Wilkinson power divider utilizing a multiple-resonant technique. Additionally, the session addresses a 220–340GHz Marchand balun with an asymmetric ground shield in 90nm SiGe BiCMOS, along with a miniaturized 150GHz branch-line coupler using capacitive compensation in quartz-IPD technology.

Abstract
This session highlights recent advances in sub-THz and THz circuits and components, spanning signal generation, frequency translation, reception, and waveguide technologies. The five papers include a 312GHz low-voltage push-push oscillator in GaAs pHEMT technology, a broadband CMOS frequency doubler with high fundamental suppression, and a sub-milliwatt receiver MMIC achieving low noise across a wide bandwidth. Complementing these active circuits are innovations in THz signal routing and multiplication, including metallized 3D-printed 1THz hollow waveguide components and a 480–530GHz balanced frequency quadrupler based on Schottky-varactor diodes integrated on a micromachined silicon membrane.

Panel Sessions
Abstract
This inter-society technical panel will emphasize the urgent need for sustainable growth within the RF industry, particularly through the development of standards for measuring the carbon footprint of RF technologies. Today, the environmental impact of RF systems extends across the full lifecycle—from manufacturing processes and material usage to deployment, energy consumption, and long-term operation. However, the absence of consistent measurement frameworks makes it difficult to evaluate, compare, and ultimately reduce these impacts in a systematic way.
The panel will bring together experts from multiple societies to explore how collective action can establish widely accepted methodologies and best practices for carbon footprint assessment in RF technologies. By working across organizational boundaries, societies can not only help define these standards but also provide strategic guidance to industry, academia, and policymakers. Such efforts are critical to ensuring that sustainability becomes a foundational consideration in future RF innovations rather than an afterthought.
Ultimately, the discussion will highlight how professional societies can play a pivotal role in shaping a greener future for the RF industry—by fostering collaboration, driving standardization, and offering direction to reduce carbon emissions across both manufacturing and operational domains.

Abstract
Artificial Intelligence is revolutionizing microwave circuit design, just as it is transforming other scientific and industrial domains. The growing number of published research papers demonstrates that the microwave community is actively embracing AI and ML across a wide spectrum of applications—from novel device modeling to virtual data generation, data management, and advanced EDA tools for circuit optimization. New commercial solutions for ML-assisted circuit design, already offer first-pass, fully automated layout generation, multi-objective optimization, and seamless multi-platform integration from device to system level. This evolving landscape suggests a progressive shift in researchers' focus from traditional design practices toward a complex interplay involving the development of custom, high-accuracy, dynamically reconfigurable models, advanced EDA algorithms, and ML workflows.
Are we ready for this revolution? Can we truly trust AI/ML-driven design? Will AI really help to uncover entirely new device concepts and circuit topologies, or will it remain a highly capable design assistant? What tools and skills are needed to become active contributors in this new paradigm?
This panel will bring together experts from foundries, model development, and EDA vendors to critically examine the pros and cons, practical implications, IP constraints and future directions of AI-assisted microwave circuit design.
