Excluding stock-based compensation costs, the company earned $10.9 million, or 13 cents a share, a penny better than analysts' forecast.

Micrel sees second-quarter revenue growth of 2% to 6% on a sequential basis, implying a top line of $69.5 million to $72.2 million. "The company's second-quarter 2006 beginning backlog is higher than the beginning backlog for the first quarter," Micrel said. "However, order lead times for the company's products remain fairly short at five to six weeks, and a relatively high proportion of quarterly revenue must still be booked and shipped within the quarter to OEM customers or resold through the company's distributors." As a result, the company said, predicting future revenue "remains difficult." Analysts project second-quarter revenue of $70.7 million. Shares were trading down $2.17 to $13.61.
