The rising complexity of 5G radios, as they evolve to support large numbers of different spectrum bands plus Massive MIMO antenna arrays, is putting RF transceiver chip providers in a strong position in the overall RAN component value chain. This has seen Analog Devices (ADI) sign a string of strategic alliances with radio unit and RAN processor suppliers, which promise to give it a pivotal role in the emerging open RAN ecosystem. One of these is with Marvell, a long-standing partner which extended the relationship to 5G Massive MIMO late last year. Marvell is building a comprehensive 5G vRAN semiconductor platform for both open and integrated architectures and will work with ADI on 4G/5G radio solutions focused on high orders…
