In what has become a familiar refrain across techland, Skyworks Solutions ( SWKS) beat analysts' top- and bottom-line numbers and issued better-than-expected guidance, but it couldn't satisfy hard-to-please investors.

After hours, the wireless chipmaker's shares were recently down 71 cents, or 6.6%, to $10.13. In regular trading, the stock closed down 5 cents, or 0.5%, to $10.84.

Fiscal second-quarter quarter sales grew 17% from last year's levels to $183.5 million, above the Wall Street consensus estimate of $176.6 million.

On a sequential basis revenue increased 5%, exceeding Skyworks' forecast for sales to stay flat.

The company reported a loss of $9.4 million according to generally accepted accounting principles. The loss reflects $17.5 million in charges for a writedown of technology licenses and for the consolidation of software development design centers. On a per-share basis, the GAAP loss amounted to 6 cents.

Pro forma earnings per share were a nickel, a penny ahead of expectations.

Chief financial officer Allan Kline predicted that sequential sales will grow by 5% in the June quarter to around $193 million, above the consensus estimate of $183.1 million.

He also forecast that gross margins will expand, as operating expenses decline as a percentage of sales.

Kline also said that the company will pay off a $45 million convertible debt note on May 12, reducing its quarterly interest expense by $1.8 million.

Earnings per share should equal 7 cents, above the 5 cents predicted by analysts.
