According to a report from iSuppli, for the first time since the research group started the yearly reports, during Q1 Qualcomm surpassed Texas Instruments as the world leader in circuited chipsets for mobile devices.

Even though it's staring down a ban on U.S. imports of certain handsets, Qualcomm sales have grown especially for handsets using its 3G technology for CDMA networks. According to iSuppli's senior analyst Francis Sideco, Qualcomm's first-quarter supremacy rests on its dominance of the EV-DO market, which TI doesn't service.

TI also posted less than stellar quarterly profits and a lukewarm revenue forecast for the quarter ahead. Qualcomm is expected to post strong financials later on today for its most recent quarter.
