MediaTek announced a share-swap merger with Ralink on March 16, 2011, and completed the acquisition effective October 1, 2011. MediaTek survived the transaction and Ralink became its wholly owned subsidiary. It was a stock exchange, not a reported cash purchase.
How the MediaTek–Ralink deal worked
MediaTek’s March 16, 2011 announcement described a merger agreement in which MediaTek would remain the surviving company and issue shares in exchange for Ralink shares. The proposed exchange ratio was one MediaTek share for every 3.15 Ralink shares, subject to shareholder approval and regulatory review. MediaTek’s announcement characterized the transaction as a share swap; the reviewed sources do not establish a cash purchase price.

Why the exchange ratio appears as both 3.15 and 3.156
The March 2011 announcement stated 3.15 Ralink shares for one MediaTek share. MediaTek’s later annual report and financial statement note give the ratio as 3.156 Ralink shares per MediaTek share. The documents reviewed do not explain the difference, so the clearest reading is to preserve the announcement’s stated figure separately from the greater precision in later filings rather than treat them as competing deal structures.

What Ralink brought to MediaTek
MediaTek presented the acquisition as a way to combine complementary technologies, expand addressable markets and add Ralink’s technology and engineering capabilities. Its annual report linked the transaction to development in networking and broadband communications. Those are management’s stated objectives, not independently measured outcomes.
