MaxLinear Linearization and Cree GaN on SiC energy amplifiers mix to create the brand new ultra-wideband 5G. to provide effectively

New GaN-on-SiC linearization solution enables 5G base stations to support more high-speed data for mobile users

CARLSBAD, Calif. & DURHAM, NC, June 23, 2021 – (BUSINESS WIRE) – MaxLinear, Inc. (NYSE: MXL), a leading provider of radio frequency (RF), analog, digital, and mixed-signal integrated circuits , and Cree, Inc. (NASDAQ: CREE), the world’s leading provider of silicon carbide (SiC) technology through its Wolfspeed business, gave breakthrough performance in combining the ultra-wideband linearization solution (MaxLin) of MaxLinear and Wolfspeed® gallium nitride (GaN ) known from Cree. on SiC mid-band power amplifiers. The new solution increases the wireless capacity of a 5G base station, supports more concurrent users and increases the speed of data transfer.

Using GaN on SiC with effective linearization accelerates the adoption of 5G by enabling significant energy, heat and cost savings through more efficient wireless transmission. The energy savings from combining Cree’s highly efficient GaN on SiC power amplifiers with a highly effective linearization solution from MaxLinear can be hundreds of watts for the massive MIMO radios that 5G requires.

“Our GaN-on-silicon carbide power amplifiers are designed to achieve high efficiency with extremely large instantaneous bandwidth in a very small form factor in the newly released 5G spectrum,” said Gerhard Wolf, senior vice president and general manager of RF at Cree Wolf speed. “Working with the MaxLinear solution, this technology represents a significant step forward in achieving superior linearity performance and will help wireless operators deliver superior levels of performance and service to wireless customers.”

The new solution addresses a significant industry challenge: implementing radio units with massive 5G MIMO arrays such as 64×64 or 32×32 while maintaining a reasonable size, weight, and performance. The newer 5G spectrum has a higher carrier frequency and wider bandwidths, which makes it more difficult to achieve high energy efficiency for radio units.

The story goes on

“We are solving a significant challenge in 5G radios,” said Helen Kim, vice president of MaxLinears Wireless Technologies & IP. “Customers need to find a way to deliver 5G mid-band capacity without a corresponding increase in cost and performance. Our energy efficient broadband linearization solution and our low power 400 MHz transceivers significantly reduce the heat dissipated from massive MIMO arrays, resulting in a much leaner, lower cost wireless solution. “

With GaN on SiC, MaxLinear’s solution offers breakthrough linearization performance for a 280 MHz channel to support the US 5G spectrum (3.7-3.98 GHz) and a 400 MHz channel to support the Asian and European 5G mid-band spectrum (3.4-3.8 GHz). With an instantaneous bandwidth of 280 MHz, the power amplifier WS1A3940 from Cree achieves an efficiency of ~ 50% with an average output power of 39.5 dBm, the MxL1600 transceiver from MaxLinear offers a sampling rate of 983 MSPS and MaxLin improves linearity by> 20 dB, to surpass 3rd Generation Partnership Project (3GPP). and Federal Communications Commission (FCC) requirements with margin. With the Wolfspeed WS1A3640 power amplifier, MaxLin also demonstrates a linearization improvement of> 20 dB at 400 MHz instantaneous bandwidth.

Cree’s WS1A3940 and WS1A3640 GaN on SiC power amplifier modules, MaxLinears MxL15xx and MxL16xx 400MHz transceivers and MaxLinears MaxLin linearization technology are solutions that enable both traditional and Open RAN innovations.
