Spreadtrum Communications, Inc. (Chinese: 展讯通信有限公司; pinyin: Zhǎnxùn Tōngxìn Yǒuxiàn Gōngsī) is a Chinese fabless semiconductor company headquartered in Shanghai which produces chipsets for mobile phones. It is the world's 17th-largest fabless semiconductor company measured by 2011 revenues.[3]

Spreadtrum has research centres in Shanghai, Beijing, Tianjin, Suzhou, Hangzhou, Chengdu, Xiamen, US, Finland and India, technical support centre in Shenzhen, and international field support offices in South Korea, Taiwan and Mexico. Its products support a broad range of wireless communications standards, including GSM, GPRS, EDGE, TD-SCDMA, W-CDMA, HSPA+ and TD-LTE.

The company originally produced chips for GSM handsets, but most of its resources are now focused on the Chinese TD-SCDMA 3G standard. In addition to GSM and combined GSM/TD-SCDMA baseband chipsets, Spreadtrum also supplies chips for two Chinese mobile TV standards: TD-MBMS and CMMB. Spreadtrum's customers accounted for 50% of TD-SCDMA handset sales in China Mobile's current round of TD-SCDMA trials.[4]

Spreadtrum was formerly a public company listed on NASDAQ, but agreed to an acquisition by Tsinghua Unigroup in July 2013 for about $1.78 billion;[5] the deal completed on 23 December 2013.[6]
