The evolution of 6G technology is set to transform wireless communication, with the FR3 spectrum playing a pivotal role. FR3 spectrum (spanning 7–15GHz) offers wide bandwidth and favorable propagation...
This talk will describe high-level design considerations for arrays operating in the W-band. Architecture challenges, technology choices, stability, power, thermal, assembly, and test challenges will ...
Beamforming and MIMO architectures add an extra dimension to transceivers for wireless communication and radar: phase shifting, as a narrowband substitute for true time delays and signal combination o...
This talk will present our work in reconfigurable beamformers and transceiver at 6–18GHz in GlobalFoundries 22FDSOI. Rather than a wideband response, we will show that reconfigurable circuits offer a ...
Wideband electronically steered arrays used in SDR-centric systems increasingly operate with large fractional bandwidth and agile scan, where phase-only steering produces frequency-dependent pointing ...
This workshop presentation reviews a highly integrated wideband direct conversion transceiver with a fully integrated synthesizer. It includes 32 elements in an 8T8R configuration for hybrid beamformi...
Phased array-based systems must support the formation of beams with precise lobes and nulls in specific locations to operate effectively in complex environments with multiple users, objects, and inter...
Beamforming antennas require precise alignment of the individual radiator elements to provide accurate beamforming with low sidelobes. For transmitters, accurate measurement of Effective Isotropic Rad...
The rapid demand for measurements at ever-higher frequencies is driving new requirements for accuracy, traceability, and integration in wafer-level test systems. With increasing circuit complexity and...
On-wafer measurements are known to be challenging and ambitious, involving several parasitic effects which degrade the accuracy of the measurements. This talk further elaborates on parasitic effects c...
