pSemi, a Murata company, and Peraso Inc., in collaboration with Richardson RFPD, an Arrow Electronics company, are publishing new information following the earlier announcement, “Collaborate on RF Solution for 5G mmWave Fixed Wireless Access” issued in June. The RF solution for mmWave fixed wireless access (FWA) customer premises equipment (CPE) uses the new Peraso PRS1520 beamformer RFIC and the pSemi PE128300 up-down converter. An application note published on Richardson RFPD’s website provides the next-phase hardware block diagram, including peripheral components, and test results of the system operating in the 26–28 GHz band.
The mmWave frequency bands provide extensive RF spectrum ideal for FWA delivering multi-gigabit services. Leveraging 5G mobile infrastructure, mobile network operators (MNOs) in many global regions are beginning to offer fixed wireless services, directly competing with cable and fiber, and reaching areas underserved by current broadband providers.
PRS1520 supports major mmWave bands and offers sufficient transmit power to meet the EIRP expectations for Class 1 CPE. In combination with pSemi’s high-performance PE128300, system developers can realize a cost-efficient RF solution for n257, n258 and n261 (24.25–29.5 GHz) bands.
“pSemi remains committed to developing industry-leading solutions and innovating for the future. This continued collaboration with Peraso is proof of our commitment to partnership and collaboration to deliver future innovations,” says Vikas Choudhary, vice president of global sales, marketing and system engineering at pSemi.
“Thanks to the collaboration with pSemi and the help of Richardson RFPD, we are on track to provide a complete reference design for 5G mmWave CPE,” says Ron Glibbery, Peraso’s CEO. “The integration and testing effort conducted so far demonstrates Peraso’s beamformer, in combination with pSemi’s up-down converter, is the right solution to meet the challenge of building a low-cost CPE.”
