USPTO Awards Patent to Merrimac fro Multi-Mix Microtechnology

Merrimac Industries, Inc. (AMEX: MRM), a leader in the design and manufacture of RF Microwave components, assemblies and micro-multifunction modules (MMFM®), announced that it has been granted a patent for its Multi-Mix® Microtechnology from the United States Patent and Trademark Office entitled “Coupler Resource Module”. This patented technology enables Merrimac to produce, highly integrated, complex RF modules, with mixtures of active and passive technology in very small, rugged form factors. The flexibility of this technology allows it to be used for a wide range of components, such as amplifiers, frequency control products, passive microwave components, and integrated subsystems.

Multi-Mix® is a proven enabling technology for microwave multilayer integrated circuits and System In A Package® (SIP®) integrated modules. Merrimac’s proprietary process for constructing RF components and integrated modules on fluoropolymer composite substrates utilizes a unique method of manufacture whereby both passive and active devices are incorporated into a homogeneous multilayer dielectric medium.

Chairman and CEO Mason N. Carter noted, “This new Multi-Mix® patent is another positive step in our mission to keep Merrimac positioned as an industry leader in the design and manufacture of highly integrated RF/Microwave Components, Modules and Subsystems.”
