MaxLinear, today announced that SAMJI, a leading provider of wireless network solutions to mobile operators or enterprises worldwide, has selected the MxL1600 family of RF transceivers and MaxLIN™ Digital Predistortion (DPD) and Crest Factor Reduction (CFR) technologies for its new Band n77 Sharing Distributed Antenna System (DAS) shared by four operators.

SAMJI’s n77 Sharing DAS series is an exciting new product line of multi-operator radio systems for public and private network deployments. With bandwidths up to 400MHz at RF frequencies from 3.6 GHz to 4 GHz, SAMJI’s n77 Sharing DAS offers class-leading flexibility in an ultra-compact size and power footprint delivered through MaxLinear’s MxL1600 RF transceiver platform coupled with MaxLinear’s MaxLIN high efficiency DPD.

The global DAS market was estimated to be US$8.4 billion in 2022 and is projected to grow to US$12.5 billion by 2030, a CAGR of 5.1% over the analysis period 2022-2030, according to the latest DAS strategic business report from ResearchAndMarkets.com.

“With the introduction of 5G globally, small cell vendors like SAMJI are challenged to quickly deliver compelling new products that support radio bandwidths of up to 10x previous solutions while reducing power consumption and system costs,” said Brendan Walsh, Vice President of MaxLinear’s Wireless Infrastructure Group. “SAMJI is one of the first vendors to release a product that successfully delivers on all these challenges and more. We are honored to partner on their innovation.”

“The close collaboration between SAMJI and MaxLinear has dramatically sped up development of our new 5G radios,” said Youngson Lim, Senior Research Engineer at SAMJI. “The programmability and performance of MaxLinear’s silicon solutions have enabled us to develop a single RF platform with the flexibility and cost effectiveness that supports our roadmap, while their technical teams provide us with the needed support that accelerates our time to market.”

More about the featured products:

MaxLinear's high-performance RF transceiver portfolio supports up to 400MHz instantaneous bandwidth (IBW) and includes the MxL16xx Quad-RF and MxL155x Octal-RF families. These transceivers are software compatible, creating a single platform solution that customers can leverage for radio applications, including macro, massive MIMO, and small cell.

MaxLinear's MaxLIN is an innovative DPD linearization solution. Its advanced machine learning algorithms exceed the 3rd Generation Partnership Project (3GPP) and Federal Communications Commission (FCC) unwanted emissions requirements with margin while delivering high PA efficiencies of >50%. This capability dramatically reduces power consumption for an 8-transceiver macro implementation by up to >10% compared with competitive DPD offerings.
