Merrimac Multi-Mix PICO Offers Multi-Chip Module (MCM) Designs to Engineers for Design Flexibility

WEST CALDWELL, N.J., June 4, 2002: Merrimac Industries, Inc. (AMEX: MRM) today announced that Multi-Mix PICO^TM offers design flexibility by offering phase shifters, IQ networks, attenuators and vector modulator reference designs to engineers who prefer open architecture designs and who desire to test their system designs quickly.

Chairman and CEO Mason N. Carter commented, "Multi-Mix PICO^TM now offers several design options to engineers who are looking for quick, flexible, low cost, surface mount integrated solutions."

"Multi-Mix PICO^TM design options:

Engineers who desire to build their own designs can now mount individual Multi-Mix PICO^TM products directly onto their own boards to test out their new system designs.
Engineers can also purchase several Multi-Mix PICO^TM products, in the form of a 'known' good module, MCM (Multi-Chip Module), pre-mounted, pre-tested, on a Merrimac board, which in turn, can be placed onto the designers circuit board. This option offers advantages in developing prototypes towards integration. The MCMs can be either surface mounted or connectorized.
The Multi-Mix PICO product line is available as a fully integrated multilayer 'known' good module, which can be surface mounted and is available on tape and reel. These modules offer a high degree of integration and provide size reduction, increased reliability due to less solder joints and minimizing interconnection lengths, better power handling, excellent temperature performance and EMI/RFI shielding.
By utilizing its building block architecture, Multi-Mix PICO^TM also provides the design engineer the option to purchase a Multi-Mix® Micro-Multifunction Module (MMFM®), which includes several of the desired signal processing functions, all integrated into a cost effective multilayer pre-designed and pre-tested 'known' good module."

Samples are available for qualified product designs.
