High-Efficiency 7 GHz Doherty GaN MMIC Power Amplifiers for Microwave Backhaul Radio Links
Vittorio Camarchia,Jorge Moreno Rubio,Marco Pirola,Roberto Quaglia,Paolo Colantonio,Franco Giannini,Rocco Giofre,Luca Piazzon,Thomas Emanuelsson,Tobias Wegeland +9 more
TL;DR: In this article, the potentialities of GaN monolithic technology for the growing microwave backhaul power amplifier market are discussed, and two GaN-based Doherty power amplifiers for 7 GHz backhaul applications are presented.
Journal ArticleDOI
Does LO Noise Floor Limit Performance in Multi-Gigabit Millimeter-Wave Communication?
Jingjing Chen,Zhongxia Simon He,Dan Kuylenstierna,Thomas Eriksson,Mikael Horberg,Thomas Emanuelsson,Thomas Swahn,Herbert Zirath +7 more
TL;DR: In this paper, the white noise floor of frequency multiplied local oscillator (LO) sources is investigated in wideband mm-wave systems. And the measured results show that the transmitter performance degrades as the LO noise floor increases.
Journal ArticleDOI
A Directly Matched PA-Integrated $K$ -Band Antenna for Efficient mm-Wave High-Power Generation
Wan-Chun Liao,Rob Maaskant,Thomas Emanuelsson,Vessen Vassilev,Oleg Iupikov,Marianna Ivashina +5 more
TL;DR: The proposed band slot antenna element with an integrated gallium nitride power amplifier is well suited to meet the high-performance demands of future emerging beamforming active antenna array applications.
Proceedings ArticleDOI
Spectrum Efficient D-band Communication Link for Real-time Multi-gigabit Wireless Transmission
Vessen Vassilev,Zhongxia Simon He,Sona Carpenter,Herbert Zirath,Yu Yan,Ahmed Hassona,Mingquan Bao,Thomas Emanuelsson,Jingjing Chen,Mikael Horberg,Yinggang Lit,Jonas Hansrydl +11 more
TL;DR: The TxlRx front-end modules were integrated in two radio units to demonstrate a real time wireless data transmission and the highest data rate achieved was 5.3 Gbit/s using 64 QAM modulation over a 1 GHz channel with spectrum efficiency of 5bit/slHz.
Journal ArticleDOI
Phase-Noise Analysis of an X-Band Ultra-Low Phase-Noise GaN HEMT Based Cavity Oscillator
Mikael Horberg,Thomas Emanuelsson,Szhau Lai,Thi Ngoc Do Thanh,Herbert Zirath,Dan Kuylenstierna +5 more
TL;DR: In this paper, an ultra-low phase-noise oscillator based on a GaN HEMT monolithic microwave integrated circuit reflection amplifier and an aluminum cavity resonator is reported.
