Broadband transceivers sign higher 5G base stations

An industry-leading 5G digital platform and world-class broadband radio frequency (RF) transceiver technology are expected to deliver fully optimized 5G base station solutions.

Marvell and Analog Devices Inc (ADI), based in Bermuda, are expected to offer fully integrated digital 5G front-end ASIC or application-specific integrated circuit solutions as well as tightly coupled RF transceivers. For this collaboration with ADI, Marvell is providing its digital 5G platform to develop the next generation of Radio Unit (RU) solutions. The solutions include baseband and RF technology that is optimized for a variety of functional divisions and architectures.

“ADI has always been a leader in wireless technology,” said Vincent Roche, president and chief executive officer (CEO) of Analog Devices. “In our collaboration with Marvell, we see an enormous opportunity to optimize the 5G RF and digital chain for the benefit of our mutual customers. With the solutions that we develop in collaboration with Marvell, our customers can develop highly optimized, high-performance products for this dynamic market. “

The increasing complexity of 5G radio units, which is caused by the enormous use of MIMM antennas (multiple input, multiple output) and the requirements for the millimeter wave spectrum, poses challenges for the designs for RF and radio networks. A 5G network operates in the microwave band of the electromagnetic spectrum for its many users. Microwaves are between 300 megahertz and 300 gigahertz. Cell phones use microwave band frequencies from 900 MHz to 1.8 GHz.

The 5G radio access network, which includes mmWave transmission, and the core network are the two main components of a 5G network. These two components are also used by the predecessors of the 5G network, 3G and 4G. For consumers, 5G promises bandwidths of up to 100 megabits per second. In May 2019, ADI introduced a new solution for mmWave 5G, which the company claims represents the highest level of integration available to reduce design requirements and complexity in the next generation of cellular network infrastructure. The solution combines ADI’s advanced beamformer IC, up / down frequency conversion and additional mixed signal circuitry. ADI said its mmWave legacy enables its customers to leverage world class applications and system design to optimize complete lineups for thermal, RF, power, and routing considerations.

“Marvell is excited to partner with ADI to seize a significant opportunity for the next wave of 5G network architectures,” said Matt Murphy, President and CEO of Marvell. It is expected that optimized partitioning of the RF and mixed-signal technology with both digital ASIC and baseband silicon will be required to meet the low performance, size and cost requirements for 5G. Murphy added, “Marvell’s leadership in baseband, digital ASIC and transport processors combined with ADI’s RF transceiver technology creates an industry-leading architecture for 5G OEMs looking to reduce time-to-market.”
