Tu4F-1: Recent Data Downlink Antenna Developments for Small Satellites with Focus on NewSpace and CubeSat Applications
This keynote presentation will provide an overview of commercially available data downlink antennas developed for small satellites, with particular focus on NewSpace and CubeSat applications. Various ...
Tu4F-2: Simultaneous Multibeam Operation in 19.5GHz SATCOM Receive Phased Arrays Using Orthogonally-Coded Nested Subarrays
This paper presents a novel approach to generating multiple simultaneous beams from a single phased array aperture and a single RF signal path. Simultaneous beam patterns can be synthesized using orth...
Tu4F-3: A Heterogeneous Transceiver in 0.1µm D-Mode GaAs and 65nm CMOS for SATCOM Phased Arrays
A 4×2 phased array using a 0.1 µm GaAs pHEMT and 65 nm CMOS processes transceiver (TRX) front-end (FE) for potential satellite communication applications is designed. This work investigates novel conc...
Tu4F-4: Polarimetric Spectrometer Receivers for Remote Sensing of Ionospheric Currents
The solar storms create ionospheric currents around the poles of the Earth. These currents cause variations in the local magnetic fields that give rise to the Zeeman frequency splitting of the oxygen ...
Tu4F-5: An Interleaved 1×8 Dual-Polarized L-band Phased Array with Digital Transmit/Receive Beamforming Using RFSoC
A 1×8 dual-polarized L-band transmit-receive phased array, comprising four interleaved arrays, combined with an radio frequency system-on-chip (RFSoC) is presented. Full simultaneous digital beamformi...
WSL-3: Transformer-Based mm-Wave PA Design in CMOS, InP and GaAs
This talk will discuss several mm-wave PAs, implemented and measured in 16nm FF, Bulk CMOS, InP and GaAs. The common-theme will be the use of transformers to reduce the area, to lower matching-losses ...
We1B-1: A MIMO Perspective of Phased Arrays and its Applications
Phased arrays are most often thought of as just a way to electronically focus, steer, direct and receive energy. In this traditional modality, all the antenna elements work cooperatively to illuminate...
We1B-2: A 1.53-mm² Fully-Integrated Wi-Fi 7 Front-End Module with 1.65-dB NF and 41.9% FBW in 0.25-µm GaAs p-HEMT Technology
This paper presents a highly integrated front-end module (FEM) in a 0.25-µm GaAs p-HEMT process for Wi-Fi 7 applications. The design incorporates a wideband low-noise amplifier (LNA) with a feedforwar...
