ROGERS, CT -- Sales at Rogers Corp.'s Printed Circuit Materials unit fell 6.7% year-over-year in the second quarter on weaker demand in the wireless infrastructure sector.

For the period ended June 30, sales at the unit totaled $40.5 million. Rogers, which supplies printed circuit laminates, particularly for high-frequency and microwave applications, said higher demand for automotive radar safety and base station antenna applications were offset by lower base station deployments.

Overall, the company reported net sales of $126.7 million from continuing operations, within previous company guidance of $125 million to $132 million. Profits fell by almost half, to $6.4 million. The company reported gross margins of 29.1% in the quarter, compared to 33.8% in the second quarter 2011.

Rogers president and CEO Bruce D. Hoechner said "The current business climate uncertainty is tempering our third quarter topline guidance, which we forecast will increase to between $127 million to $135 million."
