For customers working in industrial applications, they require this combination of flexibility and cost-effective power supply design.”
Qorvo has been deeply involved in the UWB field for many years and has rich technology and manufacturing experience. The company's products have been widely used in more than 40 vertical markets, with a market share as high as 70%. Among them, smartphone positioning, car keyless entry and spatial audio technology based on UWB technology innovation are attracting more manufacturers to invest in research and development.
Marketing Manager Dash Kong said: "Through the acquisition of Decawave and its own technology accumulation, Qorvo has become a leader in the UWB field. The company's UWB products are providing support for many well-known brands at home and abroad. In the future, combined with Qorvo's strong strength in the RF front-end, we will also It will provide customers with IoT connection capabilities that are easier to develop and have more stable signals.”
In the past few years, cars have been transitioning to electrification and intelligence. Qorvo, with its deep accumulation, has also successfully entered this market and plays an important role in the design of Internet of Vehicles applications, providing complete connectivity (including V2X and Wi-Fi). system solutions.
James Huang, senior sales director of Qorvo's High Performance Products Division, said: "The initial automotive electronics may be more about audio and video entertainment systems. With the development of automotive intelligence, it is very likely that cars will develop into a new category after computers and mobile phones. The Internet platform. Starting from RF, which Qorvo is good at, and combining the multiple product lines integrated by the company’s mergers and acquisitions, Qorvo has more product directions in automotive applications.”
Relying on its own high-power HBT amplifier technology, SAW and BAW filter technology, SOI design capabilities and industrial control capabilities and other technical and packaging and testing advantages, coupled with a series of automotive certification product experience, Qorvo can provide the industry with high-quality Highly integrated single-chip solutions support the communication functions required in automotive scenarios, and these devices can also provide protection throughout the entire life cycle of the vehicle.
In the entire V2X design and deployment, the biggest challenge comes from too much interference caused by too many frequency bands, which requires the support of various filters, switches, amplifiers and other technologies. Qorvo's process advantage lies in the high degree of integration of these separate architectures into the entire single chip. With the conversion from 4G to 5G, the demand for throughput increases. As a type of terminal equipment, automobiles also begin to require MIMO product design to improve its performance. When supporting multiple standards at the same time, Qorvo's highly integrated advantages and packaging The advantage of not interfering with each other is fully reflected.
In the smart car market, Qorvo has also launched various applications for smart cockpits. The first is pressure sensors. New touch methods can reduce touch errors for users and bring a more intelligent experience. Qorvo's human-computer interactive touch control method is more accurate and is less susceptible to external misleading, so the control of the car will be better. These applications will be reflected in the steering wheel, car keys, doors, etc. Of course, our pressure sensing will also be used in other consumer products, including mobile phones, platforms, computers, headsets, etc. Intelligent and safe car body entry, cockpit biological detection, etc. will also become a new flashpoint for UWB. James Huang introduced. Another major application in Qorvo cars is power supply. From electric vehicles, charging piles and in-cabin power applications, Qorvo has a relatively comprehensive product line.
"Qorvo's technology and product portfolio are uniquely positioned to support advanced automotive platforms and can provide partners with AEC-certified, high-quality products that meet customers' drive architecture and requirements. Qorvo is currently working with many automotive OEMs and tier 1 Manufacturers cooperate to build a complete automotive ecosystem and will further deepen their investment in automobiles in the future.”
Unique advantages in high-pressure situations
SiC has always been regarded as the "ideal material" for power devices by the industry and is highly anticipated. Especially in high-voltage applications, SiC has unparalleled advantages. Qorvo has also become an important promoter of SiC applications through the acquisition of UnitedSiC.
Sam Koh, Sales Director of the Silicon Carbide Business Unit, introduced that currently, Qorvo’s silicon carbide power devices mainly fall into two categories: 650V/1200V/1700V SiC Schottky diode product portfolio, and 650V/750V/1200V/1700V SiC FET product portfolio. . Most of these products have automotive grade AEC-Q101 certification, which can assist the research and development of new energy vehicles. It is worth mentioning that the company’s latest 750V SiC FET device has the world’s lowest on-resistance of 5.4 (mΩ). It is packaged in a TOLL package and is based on a unique Cascode circuit structure (i.e. cascode). SiC JFET and Si MOSFET are co-packaged inside a device, which can take full advantage of the high efficiency advantages of wide bandgap switching technology and the simplified gate-level drive of Si MOSFET.
Michael Zhou, senior application engineer of the Silicon Carbide Division, focused on the advantages of Qorvo SiC products compared with other similar products. Qorvo's SiC products adopt Cascode structure, which has the lowest on-resistance and excellent switching performance in the industry. Silicon-based Mosfet, IGBT and SiC Mosfet are all compatible. In terms of design, these products use advanced wafer thinning processes and silver sintered core tube connections to achieve excellent thermal performance, and have built-in body diodes and gate integrated ESD protection with excellent conduction voltage drop, which improves efficiency while Bring security and protection.
These high-performance products create extremely high efficiency and performance in applications such as EV chargers, DC-DC converters and electric drives, telecom/server power supplies, frequency converters and solar photovoltaic (PV) inverters.
Finally, Sam Koh concluded that Qorvo’s SiC FET has four major differences:
First, it does not require a negative gate drive voltage, which can minimize the difficulty of transitioning from silicon to silicon carbide, save engineering component costs, and provide design flexibility;
Second, compared with SiC MOSFET, it has lower on-resistance to provide lower conduction loss, and also has faster switching speed, which can provide lower switching loss; compared with silicon superjunction MOSFET, SiC MOSFET The technical performance of the products is very good. Although the cost is about 30-40% higher than that of Si-based products, they are still market competitive;
Third, Qorvo SiC has lower impedance and faster switching speed, which can help customers' products achieve higher efficiency and higher power density. It can be easily upgraded using the same package and can also use a smaller size. and radiators to reduce system costs;
Finally, compared with other competitors, due to the smaller size of SiC JFET under the same conditions, Qorvo can theoretically produce 2-4 times more chips per wafer, with better SiC substrate utilization and higher manufacturing throughput. quantity.
