GREENSBORO, N.C. — RF Micro Devices, a global manufacturer of radio systems and solutions for mobile communications, has opened a customer support center in Shanghai, China.

China is the world’s largest market for cellular devices.

The center is designed to support RFMD operations elsewhere in China and in Taiwan. Staff includes technical sales, sales management, application support and customer support.

“RFMD’s continued expansion into the Greater China market demonstrates our focus on supporting the local handset manufacturers in this territory,” said Greg Thompson, RFMD vice president of worldwide sales and applications. “This new location will expand and strengthen our technical and systems support, while helping to advance the integration of complementary radio functions and applications in cellular handset designs.”

RFMD now employs more than 900 people in China and Taiwan, including sales and support centers in Shenzhen, China, and Taipei, Taiwan, and an assembly and testing facility in Beijing.
