Merrimac Receives 77GHz Circuit Order for Automotive Adaptive Cruise Control Sensor

WEST CALDWELL, N.J., January 22, 2002: Merrimac Industries, Inc. (AMEX: MRM), announced today that its wholly-owned subsidiary Filtran Microcircuits Inc. has received a production order for the year 2002 to provide customized circuitry that will be employed in an Adaptive Cruise Control Sensor manufactured by M/A-COM for the "Distronic System" used in the Mercedes Benz "S, E and C Class" series of automobiles. The device, also known as "Forward-Looking Radar," is a wireless sensor that provides driver assistance while improving safety and security. It senses objects in front of the auto, determines the rate of change of the vehicle versus the objects ahead and enables the Mercedes "Distronic System" to adjust the vehicle speed for a safe following distance.

Mason N. Carter, Chairman and CEO of Merrimac commented, "Filtran has teamed with M/A-COM to optimize the design by providing an innovative 77 GHz high-frequency, fine-line circuit solution. This solution is consistent and repeatable in manufacturing production quantities. Since the project began, Filtran has been supplying fine-line etched circuits, and has continued to enhance its production techniques in order to maintain tight delivery schedules. We are committed to supporting M/A-COM, a leader in Adaptive Cruise Control (ACC) systems, on this program along with other high-frequency short radar distance applications."

David Merrill, Senior Supply Base Specialist stated, "M/A-COM selected and continues to work with Filtran because it is one of the few companies that can create the fine-line circuits required by the millimeter-wave system and deliver in high quantities in a timely manner. The design requirements for these circuits are clearly a manufacturing challenge and will strain the standard process capabilities of many PCB manufacturers. The circuits form a portion of the millimeter-wave radar that is the critical sensor element for the system. At such a high operating frequency, the circuits require extremely tight tolerances and precision etching that is beyond the capabilities of most fabricators."
