Merrimac Awarded $430,000
Multi-Mix® Order For Military Satellite

WEST CALDWELL, N.J., January 16, 2007: Merrimac Industries, Inc. (AMEX: MRM), today announced that it has received an order for $430,000 to supply several Multi-Mix® Microtechnology products for a next generation military communications satellite program.

The satellite communications system is designed to significantly improve communications for mobile U.S. forces. Merrimac was selected based on the company’s ability to provide dividing and combining devices that are able to handle very high RF power, provide very low insertion loss, and are contained within a caseless fusion bonded assembly. The program significantly improves communications for warfighters while maintaining backward compatibility to the existing communications systems for the U.S. Department of Defense.

Chairman and CEO Mason N. Carter commented, “We are delighted that our Multi-Mix® solution will assist in enhancing the communications systems with improved connectivity. We are proud of our role and contributions to the satellite program by improving ubiquitous voice, video and data to warfighters on the ground, in the air, and on the seas.”
