Microsemi Corp., a Santa Ana semiconductor manufacturer, reported a loss of $707,000 for its fiscal third quarter ended July 2, its first quarterly loss in eight years. The loss contrasts with earnings of $548,000 for the corresponding quarter the year before. The firm put the primary blame for the loss on the cancellation of a $10-million contract with a San Diego-based unit of General Instrument Corp. Microsemi had expected the contract to contribute $1.2 million in sales and $400,000 in gross profit for the latest quarter. David R. Sonksen, a Microsemi vice president, said the company has filed a lawsuit against General Instrument, claiming that the New York-based electronics firm breached the terms of its contract with Microsemi. Microsemi’s revenues grew 21% to $26.4 million for the quarter, up from $21.7 million for the period in the previous year.
