What was the percentage increase in revenue for Qorvo's mobile products segment in the 2020-Q2 quarter compared to the previous quarter 
r outstanding quarter as our technology investments, portfolio management and operational discipline continue to yield strong and consistent results. Upside during the quarter was attributable to new product cycles across our largest customers. In mobile products, the trend toward integration is driving our industry and integration is all the more important with the introduction of 5G.
Qorvo is securing significant content in 5G smartphones with our premium technologies and are highly integrated modules, enabling our customers to enhance system performance, overcome design challenges and bring their smartphones to market faster than ever. In IDP, our markets are supported by secular trends, including the deployment of 5G as well as the proliferation of IoT, the adoption of WiFi 6 and the performance advantages of GaN technology in defense, broadband and massive MIMO base station applications. Looking at our September quarter by business, our performance in mobile products was driven by multiple customers and product segments. Samsung was a standout as we expanded our participation in their mass market phones.
Qorvo's broad portfolio of enabling technologies, coupled with a robust supply chain and solid product execution, is allowing us to solve our customers most challenging problems across all tiers of their portfolio. To that end, we're enjoying significant traction with our four largest customers in China, designing our low, mid-high and ultrahigh band solutions into their upcoming 5G smartphones. Our wins are broad-based and our solutions are mated with all the major chipset providers, including SLSI, Qualcomm, MediaTek and HiSilicon. In mobile WiFi applications, we are ramping our recently launched WiFi 6 FEMs in support of multiple leading China-based smartphone OEMs.
Turning to IDP. In our defense business, we are a lead participant in a U.S. government program to advance the state-of-the-art and RF integration packaging and test. We are also increasing our GaN opportunities with the U.S.
primes, and we secured wins for our GaN amplifiers and integrated front-end modules for X-band and Ka band, defense radar and communications programs. In infrastructure, the ramp of 5G appears to be rolling out faster than the ramp of 4G. Activity is primarily in the sub-six gigahertz frequencies, and Qorvo's GaN technology is increasingly the technology of choice. During the quarter, we secured new GaN design wins for sub-six gigahertz, massive MIMO deployments, expected to span multiple years.
Among China-based carriers, it's been widely published that China Unicom and China Telecom will share cell sites to accelerate 5G deployments. This development will drive the need for broader band and higher power amplifiers, favoring Qorvo's GaN solutions. GaN enables operators to drive more power through smaller form factors and achieve better performance at higher frequencies. In IoT, the ratification of WiFi 6 is a catalyst for the industry and design wins for Qorvo's WiFi 6 solutions are building.
During the quarter, we launched the world's first WiFi 6 dual-band front-end module and the world's first WiFi 6 iFEM for CPE applications expanding our product portfolio for retail, enterprise and network operators. In automotive, we commenced production shipments of our WiFi FEM supporting multiple automotive OEM platforms. And notably, our V2X co-existence BAW filters for 5.9 gigahertz were recently selected by a top automotive OEM for models shipping next calendar year. With the continued expansion of IoT devices and smart home control, Qorvo is uniquely positioned to combine WiFi 6 iFEMs with advanced filtering and multi-protocol SoCs into highly integrated solutions reducing time to market and supporting smaller end devices.
We expect many of today's gateway devices and voice assistance products to incorporate all of these technologies enabling interim control of the entire smart home. In programmable power management, Qorvo is at the forefront of multiple trends, including the trend toward brushless D.C. motors. During the quarter, w
