Qorvo, the world's leading provider of connection and power solutions, successfully held a media day in Beijing on April 11th with the theme of "Spring light leads, everything becomes more" core ". Qorvo relies on its strong technological capabilities and ability to capture market trends, providing a variety of technological applications and innovations for the industry and consumers, delving into multiple application fields such as mobile communication, infrastructure, power management, the Internet of Things, automotive electronics, and consumer electronics. This event showcases innovative achievements in multiple fields and delves into cutting-edge technologies and market dynamics.

Fast connection, Wi Fi 7 opens up a new era of wireless networks

Qorvo continues to meet the needs of consumers in the smart home market and promotes seamless connectivity between smart home devices. Qorvo utilizes exciting cutting-edge technologies such as Wi Fi 7, Matter, and Ultra Wideband (UWB) to develop interconnected products and devices for smart home automation, secure access, and adaptive experiences.

On January 9, 2024, the Wi Fi Alliance, an organization that maintains and develops Wi Fi standards, officially announced that it has completed and launched the certification of Wi Fi 7 advanced wireless standards. Applicable terminal products can officially obtain Wi Fi 7 certification and be sold based on it. As the next generation wireless communication technology standard, Wi Fi 7 introduces breakthrough technologies such as 320MHz bandwidth, Multi Link Operation (MLO), 4096-order Orthogonal Amplitude Modulation (4K QAM), and flexible channel selection, which will bring higher data transmission rates, lower latency, and stronger network connection stability, providing users with a smoother and more efficient network experience.

Qorvo's technological innovation has made significant progress in this field, not only providing complete wireless front-end RF Module (FEM) and Filter solutions, but also balancing the advantages of low power consumption and small packaging, which can provide greater space and flexibility for product development.

Wi Fi 7 has brought numerous technological breakthroughs, but it also puts higher demands on RF front-end, such as the need for more front-end modules (FEMs), achieving at least -47dB of EVM, compatibility with digital pre distortion (DPD), efficient utilization of discontinuous spectrum, and enhanced filtering performance to improve signal isolation.

Jeff Lin, Senior Marketing Manager of Qorvo's Asia Pacific Wireless Connectivity Business Unit, stated in a speech that "in order to address the new challenges of Wi Fi 7, Qorvo has adopted a Non Linear FEM+DPD solution, which not only effectively solves the problem of EVM, but also achieves significant improvements in power efficiency. For example, using Qorvo's nonlinear FEM's three frequency 12 stream router is expected to save about 6 watts (~6W) of power. In addition, Qorvo has provided a series of specialized solutions for different radio frequency bands (from U-U-6, Wi Fi 6E, and Wi Fi 7)." Filter products from NII-1 to U-NII-8. "

Jeff Lin introduced Qorvo's Front End Module devices that comply with Wi Fi 7 specifications, as well as the Body Acoustic Wave (BAW) filters that cover the entire 5GHz (UNIII1-3) and 6GHz (UNII5-8) range. Qorvo's FEM module includes two types: linear and nonlinear. Linear Wi Fi 7 FEM has excellent linearity and features of low power consumption, small packaging, and high integration; Non Linear front-end RF modules can significantly reduce power consumption while maximizing PAE. This innovative nonlinear front-end RF module scheme adopts digital pre distortion compensation technology, which can achieve performance comparable to linear FEM with almost no processor power consumption and higher efficiency.

Improving efficiency through "intelligence" and improving battery life and safety through BMS solutions

Currently, more and more devices are gradually shifting from traditional internal combustion engine driven or AC powered to more flexible and efficient battery powered modes. In this context, how to ensure the safety, stability, and service life of batteries has become a focus of industry attention. Qorvo continues to deepen its expertise in the power supply field, meeting the power supply, protection, and control needs of industrial, corporate, consumer electronics, and automotive sectors through a rich product portfolio such as power management chips (PMICs), power outage protection (PLPs), DC/DC regulators, battery management, intelligent motor control, and silicon carbide products. At the same time, Qorvo also provides QSPICE software for simulation and mixed signal simulation to improve the efficiency of engineers. Qorvo Power products can provide low-power, compact, and efficient solutions for the industry.

In terms of intelligent battery management technology, Qorvo innovatively integrates high-performance MCU and analog front-end (AFE) into a single chip, which not only simplifies the system architecture, but also improves system performance, reliability, and intelligence level. This is the industry's first BMS solution that can support precise management of up to 20 series of battery cells on a single chip. Qorvo's BMS solution emphasizes integrated design by integrating algorithms such as Fuel Gauging, SOC, and SOH into the chip, effectively improving the accuracy and speed of data collection and calculation, and enhancing the flexibility of the battery management system.

As of now, Qorvo BMS chip products have mass-produced two series: PAC2214x and PAC2514x, both of which adopt a single chip solution. Among them, PAC2214x is equipped with Arm Cortex-M0 MCU, with a main frequency of 50MHz and a Flash capacity of 32KB; PAC2514x adopts Arm Cortex-M4 MCU, with a main frequency increased to 150 MHz and a Flash capacity of 128KB. At the same time, in response to the two major requirements of safety and long endurance for battery management, Qorvo's BMS chip optimizes and manages battery efficiency and lifespan based on six functions: charge and discharge management, short circuit protection, overvoltage protection, battery monitoring, battery balancing, and low-power control.

Yichi Zhang, Senior Account Manager of Qorvo, stated, "Qorvo's single-chip battery management solution adopts mixed digital and analog technology, integrates controllers, storage, and communication interfaces, and can provide comprehensive charge and discharge control and monitoring for up to 20 series connected battery packs (lithium-ion, lithium polymer, and lithium iron phosphate, etc.). With abundant software and hardware development resources, this solution can greatly reduce customer development cycles, reduce product costs, and improve product reliability and flexibility."

"The Sensor Fusion solution is not affected by most environmental factors and is suitable for any material. It has the characteristics of high precision, high sensitivity, high linearity, and ultra-low power consumption, which can transform traditional touch buttons into fashionable, intelligent, and reliable operating interfaces," said Renado Lei of Qorvo in a speech

Qorvo's Sensor Fusion solution aims to create a three-dimensional human-computer interaction experience with higher integration, consistency, and reliability, which can be widely applied in multiple fields such as smartphones, AR/VR, cars/two wheelers/u Mobility, wearable devices, and smart homes. In terms of smartphones, they can be applied to edge touch, 3D touch, and screen wake-up functions, and novel interaction methods can open up new ideas for industry innovation. In vehicle design, Sensor Fusion combines pressure sensor technology with intelligent surfaces, and the anti accidental touch feature not only enhances the driving experience and driving safety, but also further enriches the user experience. In wearable products, this technology can overcome the challenges brought by traditional capacitive touch and sliding control, achieving a lighter, simpler design experience. In smart home applications, this technology is equally crucial, especially in terms of waterproofing and anti fouling. Sensor Fusion provides high sensitivity and accuracy, making human-computer interaction more convenient, intelligent, and smooth.
