Technical Sessions
The late-breaking news session features four fast-tracked papers highlighting advances across RFTT topic areas. It opens with an inductor-less LNA using a gm-boosted common-source stage followed by a paper then addresses 22 nm CMOS layout challenges to realize compact single-, dual-, and octa-core 120 GHz VCOs. After that, wideband components for a Tokamak edge-scanning reflectometer will be presented. The session will conclude with a fully connectorized InP amplifier module with bandwidth from DC to 189 GHz.

Technical Sessions
This session opens with an invited keynote talk that sets the stage for the technical contributions that follow. The subsequent papers highlight recent advances in acoustic resonator and filter technologies targeting highly integrated and reconfigurable RF front-ends. Topics include bi-layer A3-mode acoustic resonators operating at 18GHz with a near-zero Temperature Coefficient of Frequency (TCF) and high electromechanical coupling, IDT-based mm-wave resonators with large impedance ratios and wide frequency offsets, and miniature reconfigurable acoustic RF couplers. Further contributions address arbitrarily configurable group-delay in acoustic devices and the generalized synthesis of double-ladder acoustic filters, including the demonstration of a high-performance dual-band duplexer on LTOI using a hybrid BAW-assisted wideband bandpass topology.

Panel Sessions
Recent advances in artificial intelligence (AI) and machine learning (ML) are transforming the way wireless components and complex electromagnetic (EM) systems are conceived, designed, and deployed. This session explores how ML-enabled optimization techniques are redefining applied electromagnetics, spanning the full pipeline from computational electromagnetics (CEM), uncertainty quantification (UQ), and antenna design to impactful applications such as magnetic resonance imaging (MRI), orthopaedic diagnostics, and remote sensing of snow and environmental parameters. By embedding AI and ML into EM modeling and optimization workflows, engineers can accelerate design cycles, navigate high-dimensional design spaces, and achieve performance levels that are difficult to reach with conventional approaches.
Beyond algorithms, the session emphasizes the critical role of data in driving the quality, robustness, and trustworthiness of AI-based solutions. High-fidelity simulation data, measurement-driven datasets, and hybrid physics-informed approaches are discussed as essential enablers for reliable learning and generalization. Attention is also given to the challenge of bridging ambition and deployment—moving AI-enhanced EM techniques from proof-of-concept demonstrations to deployable, validated systems operating under real-world constraints.
