were among technology's winners Tuesday, rising 15% after the company said that its Electric Fuel Battery subsidiary received a contract to supply up to $24 million in zinc-air batteries and adapters to the Defense Department.

Sirenza Microdevices

( SMDI) fell 12.5% after the company slashed its first-quarter sales outlook. The supplier of radio-frequency components now expects sales of $12 million to $12.5 million, down from previous guidance of $15 million to $16 million. Analysts polled by Thomson First Call are expecting earnings of 3 cents a share on sales of $15.5 million. "Given the strength we saw in our business in 2004," the company said, "we are disappointed that our sales have not tracked the forecasts provided by us by our major OEM customers for the first quarter." Sirenza said that several factors hurt its results, but lower-than-expected demand and deferrals of previously forecast orders hurt results the most. Sirenza plans to release its second-quarter results on April 19. Shares traded down 47 cents to $3.30.
