An Antenna-to-Bits F-Band 120-Gbps CMOS RF-64QAM Receiver

An Antenna-to-Bits F-Band 120-Gbps CMOS RF-64QAM Receiver 150 150
Author(s): Youssef O. Hassan, Mohammad Oveisi, Zisong Wang, Payam Heydari

Abstract:

A CMOS 100–140-GHz end-to-end receiver (RX) is presented that integrates the antenna input all the way to the bitstream output, while demodulating 64QAM/16QAM/QPSK entirely in the analog domain. A sequential asynchronous demodulation method enables 120-Gbps operation at a notably small baseband power consumption. Fabricated in a 22-nm FDSOI …

Two 7–13-GHz GaAs-SiGe Four–Channel Beamforming Chiplets With/Without Metallic Interlayer Shields

Two 7–13-GHz GaAs-SiGe Four–Channel Beamforming Chiplets With/Without Metallic Interlayer Shields 150 150
Author(s): Nengxu Zhu, Yiting Zhang, Genyin Ma, Fanyi Meng

Abstract:

This letter presents two 7–13-GHz GaAs-SiGe four-channel beamforming chiplets to minimize the chip area. The chips integrate GaAs-based power amplifiers (PAs) and low-noise amplifiers (LNAs) with silicon-based phase and amplitude control modules using gold bumps. To mitigate coupling between the metal patterns of the heterogeneous chips and avoid interference with …
