Qualcomm expects revenue in the quarter ending March 27 to be $1.35bn to $1.4bn, compared with its previous range of $1.35bn to $1.45bn. Earnings should be $0.26 to $0. 28 a share, up from its previous estimate of $0.25 to $0.27 a share. Analysts had been expecting earnings of $0.27 a share on revenue of $1.42bn.

The San Diego, California-based company also said average prices in its technology licensing unit were lower than previously estimated.

Qualcomm is a developer of technology used in mobile phones, and it derives revenue from selling licenses to various wireless technologies, including code-division multiple access and WCDMA.

The company said that based on reports from licensees, it expects to collect royalties on 51 million to 52 million CDMA/WCDMA units at an average selling price of $206 in the quarter, down from its previous estimate of 46 million to 49 million units at an average selling price of $214.
