This paper presents a baseband to D-band wireless link based on transmitter module integrating 45-nm CMOS channel bonding chipset and high-gain antenna in PCB technology. The realized using commercial receiver at 42 cm achieves data rate of 57.6 Gb/s multi-channel 16-QAM with transmitting energy efficiency 27.4 pJ/b.
We present two high-efficiency baseband (BB)-to- <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${D}$ </tex-math></inline-formula> -Band transmitting systems based on a novel channel-aggregation architecture. They comprise first integrated circuit (IC) for channel aggregation at intermediate frequency (IF) and two-channel 45-nm CMOS transmitter (TX) flip-chipped antenna-in-package (AiP), which illuminates...
This letter presents an energy-efficient system with a transmitter and receiver comprising multichannel integrated circuits (ICs) in 45-nm CMOS technology antennas-in-package feeding high-directivity planar lenses. Data rates up to 56 Gb/s are demonstrated over 1-m point-to-point link using full-digital communication system. The active integrate multiple local oscillator generators for implementing channel-aggregation architecture that provides large radio frequency (RF) bandwidth (BW)...
The D-band (110-170GHz) is intended to provide tens of GHz bandwidth for beyond 5G very high data rate communications. huge available band split into multiple aggregated sub-bands. Managing such a number bands difficult using conventional heterodyne receiver. A different approach proposed here relying on analogue projection in wavelet basis. In this paper, the signal Walsh/Hadamard domain considered. paper shows that channels parallelized Walsh analog architecture can relax constrains and...
This paper presents an energy-efficient wideband Vband channel-bonding up-converter. The circuit, fabricated in 45nm CMOS RFSOI technology is composed of four lanes and output hybrid combiner based on differential coupled lines. circuit has I Q inputs each one gets up-converted to a different channel at V-band the output. required LO frequencies (58.32, 60.48, 62.64 64.48 GHz) are generated onchip using high integer number frequency multiplication from common reference input at2.16 GHz that...
