Abstract

This session covers advances in microwave technologies related to quantum computing. The session begins with two papers relevant to quantum computing readout. First a cryo-CMOS single-sideband upconverter is presented for qubit readout waveform generation and then the systematic design of parametric amplifiers using electromagnetic- and schematic-level simulations is described. Next, a wideband cryogenic VCO for use in qubit control/measurement systems is presented. This is followed by a description of research in cryogenic RF-over-fiber links. Finally, the session concludes with the presentation of an high-coherence architecture for packaging superconducting quantum processors

Abstract

Al Katz passed away on the morning of June 20, 2024, the day he had been scheduled to give a presentation at IMS'24. Today we remember Al Katz and his work on analog linearization. The session will begin with recollections by his widow Sally. Amateur radio was an important factor in Al's becoming an engineer, so we will next present his accomplishments as a radio amateur. Al's work on linearization led to the formation and growth of the Linearizer Technology Company, which will be the next topic of discussion. The fourth segment provides an overview of analog linearization and the current state of the art. Finally, members of the audience will be encouraged to give their recollections of Al Katz.

Abstract

This session explores new approaches for sub-THz and THz signal generation, spanning diverse technologies and architectures. The first paper presents a 4-240 GHz InP variable-gain amplifier employing an analog-controlled input attenuation network for versatile performance tuning. Next, a 4-420 GHz distributed amplifier MMIC in 20-nm InGaAs-on-Si HEMT technology achieves 11±2 dB of gain. A 280 GHz sub-harmonic injection-locked oscillator in 45 nm CMOS PD SOI demonstrates robust frequency generation. Finally, a 300 GHz-band single-balanced resistive mixer module in 60-nm InP HEMT features LO leakage suppression. Collectively, these designs pave the way for next-generation THz communication systems.

Abstract

This session explores advanced antenna and surface technologies addressing key challenges in next-generation wireless communication, including energy efficiency, adaptability, and sensing-communication integration. Session includes first paper for shape estimation and beam correction in flexible phased arrays, followed by a dual-polarized true-time-delay-based Reconfigurable Intelligent surface (RIS), chirp-based beamwidth control in RIS for millimeter-wave systems, and a multi-feed active antenna module achieving reconfigurable polarization. Additional presentations feature a 2-bit RIS enabling polarization-based sensing and communication, a Liquid Crystal-based RIS with energy-efficient bias pulse technology. Together, these innovations demonstrate transformative potential in reconfigurable systems for future wireless networks.

Abstract

This session features the latest developments in the production of RF power at frequencies up to 1 GHz. The session begins with a survey of transistors for production of 1 kW or more of RF power. Next the session addresses operation over wide bandwidths with both ferrite-loaded baluns and continuous-mode operation of an amplifier. Techniques for driving switching-mode power amplifiers and for directly interfacing high-efficiency amplifiers to antennas are described. Finally, the session includes a comparison of EER and Doherty techniques for high-efficiency operation at VHF.

Abstract

This session brings together four papers showcasing sub-terahertz (THz) and THz signal modulation techniques for next-generation communication systems. The first paper introduces attenuator-based vector modulation strategies for phased arrays operating from 200 to 480 GHz. The second paper demonstrates a novel photoconductive solid-state plasma evanescent-mode waveguide for sub-THz phase shifting. The third paper presents a compact 8.2 mW complementary current-reusing D-band frequency quadrupler implemented in 22 nm FDSOI CMOS. Finally, the fourth paper compares wideband low-power H-band frequency doublers, with and without driving stages, also in 22 nm FDSOI CMOS, highlighting performance trade-offs. These advances significantly elevate future sub-THz communications.
