Roger Hall -- General Manager, Qorvo High Performance Solutions
Interviewer: Microwave Product Digest (MPD)
Interviewee: Roger Hall (RH)
Q
MPD: 5G Already generating revenue for some segments of the RF and microwave industry, that should increase next year. How do you think the implementation of 5G will impact the business over the next few years?
A
RH: 5G is all about increasing capacity, lower latency and improved robustness with support for higher bandwidths and higher frequencies, making it a natural fit to leverage the capabilities of GaN-on-SiC and mmWave technologies. 5G is ramping up dramatically, but there are still unknowns in many countries. There are deployments and field trials already underway, which will support capacity growth in 2019, but mmWave still has a long way to go. Technology development itself is important, but I think the right technology needs to be deployed for the right customer needs. Qorvo supports all products, and we are working with customers on their best solutions, which may be a mix of technologies. Size, efficiency and power will drive that solution. The higher the efficiency, the higher the power you can transmit or the lower the operating cost – which is where GaN’s value lies. The defense market has addressed this, but the scale and price of the commercial market is still to be determined.
QMPD: Overall, how do you think the industry is doing compared to previous years? A
RH: The industry is stable right now, and we are at the inflection point of going from low to high, leveraging the R&D investments from DARPA and defense customers. The good news is that the technology is ready; we just need to scale it up to the commercial level. Defense customers will benefit from commercial scale, so it's a symbiotic relationship. They want to understand how commercial customers can implement this technology creatively. Right now, mmWave will be used for fixed access, and we will also start to see applications for high bandwidth streaming in consumer vehicles.
QMPD: Which RF and microwave technologies will drive the industry in 2019? A
RH: The base station and mobile industries are being driven by the need for more and more data. Network manufacturers estimate that by 2022, data traffic generated by smartphones will increase tenfold. * This quest for more bandwidth requires millimeter wave technology. Higher frequencies enable wider bandwidths and therefore meet higher data demands. I believe GaN technology will continue to gain traction as it has become the solution of choice for many critical defense applications that have the same requirements as commercial applications. The integration of BAW and SAW filter technologies is also critical to meeting the challenges of more complex smartphones and mobile devices in the new era of mobile technology.
