A real-time operating module providing enhanced flexibility and capability has been proposed. The integrated RF beamforming system with an integrated transceiver module can be operated in 8Tx-8Rx mode configuration simultaneously. A series-fed structure 8 \u00d7 7 microstrip antenna array for compact size and improved directivity is employed in the RF beamforming module. The RF beamforming module incorporates a custom 28 GHz, eight-channel fully differential beamforming IC (BFIC). An eight-channel BFIC in a phased-array beamforming system offers advantages in terms of increased antenna density and improved beam steering precision. The RF beamforming module is integrated with an RF transceiver module that enables the simultaneous up-conversion and down-conversion of the baseband signal. The RF transmitter module consists of a transmitter, a receiver, a signal generator, a power supply, and a control unit. The RF beamforming system can scan horizontally from \u221250\u00b0 to +50\u00b0 with a step of 10\u00b0. To achieve an optimized beam pattern, a calibration was conducted. The transmit and receive conversion gain of around 20 dB is achieved with the transceiver module. To verify the communication performance of the manufactured integrated RF beamforming system, a real-time wireless video transmission\/reception test was performed at a frequency of 28 GHz, and the video file was transmitted smoothly in real time without interruption within a range of \u00b150\u00b0.<\/jats:p>","DOI":"10.3390\/s24061983","type":"journal-article","created":{"date-parts":[[2024,3,20]],"date-time":"2024-03-20T10:44:33Z","timestamp":1710931473000},"page":"1983","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A 5G NR FR2 Beamforming System with Integrated Transceiver Module"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9893-2150","authenticated-orcid":false,"given":"Ayush","family":"Bhatta","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Kwangwoon University, Seoul 01897, Republic of Korea"}]},{"given":"Md","family":"Kamrojjaman","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Kwangwoon University, Seoul 01897, Republic of Korea"}]},{"given":"Sanghoon","family":"Sim","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, Chungbuk National University, Cheongju 28644, Republic of Korea"}]},{"given":"Jeong-Geun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Kwangwoon University, Seoul 01897, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"335","DOI":"10.1109\/ACCESS.2013.2260813","article-title":"Millimeter Wave Mobile Communications for 5G Cellular: It Will Work!","volume":"1","author":"Rappaport","year":"2013","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3373","DOI":"10.1109\/JSSC.2017.2766211","article-title":"A 28-GHz 32-element TRX phased-array IC with concurrent dual-polarized operation and orthogonal phase and gain control for 5G communications","volume":"52","author":"Sadhu","year":"2017","journal-title":"IEEE J.
