Data pubblicazione: | 2021 | Titolo del volume in cui è pubblicato il poster: | 2020 50th European Microwave Conference (EuMC) | Da pagina:: | 1035-1038 | Abstract: | We describe the beamforming strategy and the preliminary laboratory characterization results of the beam pattern synthesized by the PHAROS2 Phased Array Feed (PAF), a 4-8 GHz PAF with digital beamformer for radio astronomy application. The PAF is based on an array of 10×11 dual-polarization Vivaldi antennas cryogenically cooled at 20 K along with low noise amplification modules (LNAs) cascaded with a multi-channel Warm Section (WS) receiver. We present the beamforming and test procedures used to, respectively digitally synthesize and characterize the PHAROS2 antenna array beam pattern at 6 GHz. The tests of the array were carried out at room temperature by directly connecting 24 antenna elements to the WS and iTPM digital beamformer in a laboratory measurement setup. | Titolo del convegno: | 50th European Microwave Conference (EuMC) | Luogo del convegno: | Utrecht, Netherlands | Periodo del convegno: | 12-14 January 2021 | URI: | http://hdl.handle.net/20.500.12386/34472 | URL: | http://www.scopus.com/inward/record.url?eid=2-s2.0-85100951084&partnerID=MN8TOARS | ISBN: | 978-2-87487-059-0 | DOI: | 10.23919/EuMC48046.2021.9337938 | Fulltext: | open |
