The latest tech casualties of SARS are Motorola ( MOT) and TriQuint ( TQNT), which in the past week have each blamed the disease for hurting sales in Asia. But RF Micro Devices ( RFMD) and Skyworks ( SWKS), which play in the same market, certainly aren't immune from the same earnings cooties -- if not now, then possibly later in the year. The two cell-phone chipmakers claim lousy business in Asia is already built into their June quarter forecasts. They've already disappointed Wall Street with (identical) forecasts for sequential sales to be flat to down 5%, issued back in April. Now, trying to shift attention away from the itchy and uncomfortable present, RFMD and Skyworks are talking up the prospects of an improved second half of the year. But with the leading cell-phone market -- China -- ailing from both SARS and a hefty inventory buildup, that doesn't make such a convincing story. At the CIBC conference in New York Monday, the leaders of the two companies put on their chipper faces. "Right now the quarter is turning out just like we expected," said RFMD chief Bob Bruggeworth in a Webcast panel discussion, suggesting that Motorola's Monday warning wasn't unexpected. "The major OEMs have a lot of optimism about the second half of the year." Skyworks CEO Dave Aldrich agreed: "Our customers are looking at a much stronger second half than first half."
