  5. 19. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hamid Yadegar Amin; [2020]
    Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

    Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.
