In this talk, highly efficient and dense 3DHI G-band (220GHz) phased arrays developed under the ELGAR program will be presented. Under ELGAR, HRL’s GaN MMICs produce 1–3W/cm² power density, while 3D i...
In 2022, ITU-R (International Telecommunication Union - Radicommunication Sector) published a recommendation document of wide beam WPT. In the same year, new radio regulation of the wide beam WPT was ...
This paper presents a broadband G-band frequency doubler implemented in 130-nm SiGe BiCMOS technology. The design features an active balun integrated with a stacked doubler-and-amplification (D&am...
MIMO and beamforming technologies are fundamental in current OFDM based 5G and coming 6G systems. When going to higher frequencies, the increased pathloss in the channel needs to be compensated with a...
We3F-3: Low-Rank Adaptation-Based Digital Predistortion of RF Power Amplifiers for Dynamic Scenarios
This paper proposes a parameter-efficient dynamic digital predistortion (DPD) model based on low-rank adaptation (LoRA). By utilizing a fixed Kolmogorov-Arnold network (KAN) backbone to capture shared...
This paper demonstrates a correlation-based RF front-end approach that leverages pump-modulated parametric frequency conversion to enable continuous-time, waveform-selective signal processing. By trea...
