Narda-MITEQ Defense Technology Solutions is positioned as an industry leader that offers advanced integrated microwave assembly (IMA) products and sub-systems to both the commercial and military markets. Every project we undertake benefits from our years of experience and world-class resources. Our strengths include:
Narda-MITEQ has pioneered the design and manufacture of Integrated Microwave Assemblies (IMAs) for more than 30 years. The first IMAs manufactured by Narda-MITEQ, referred to as classic MICs, were realized by combining several alumina-on-carrier circuits within a single machined aluminum housing. These classic MIC multifunction assemblies provided high performance and longevity, yet the constraints of higher labor/materials costs and larger footprints were prohibitive. Today, while the vast majority of suppliers for IMA products are still using this conventional technology, the Narda Defense Technology Solution has evolved to effectively eliminate the constraints of chip and wire manufacture.Our new and continually evolving proprietary MMC (Multi-layer Microwave Circuitry) technology leverages commercially available multi-layer board materials with unique interconnection techniques, along with DSP/FPGA – enabled monitor/control functions, to allow for densely packaged IMA’s and Sub-Systems in footprints previously unachievable.
MMC uses multi-layered printed circuit boards to interconnect microwave devices (MIC, SMT, or MMIC configurations) with bias, control and digital signal processing components. These complex IMAs and Compact Sub-Systems are constructed using single or stacked multi-layer boards with the microwave circuitry on the top side, and the control circuitry, conditioning, microprocessor, FPGA and DSP circuits, on the bottom. Connections from top to bottom are made with specially developed via’s, as appropriate. Narda’s MMC technology allows the creation of more complex, high performance IMA modules with tightly controlled I/O locations and unusually small form factors that facilitate integration into complex next level assemblies.
The MMC technology utilized on our module and sub-system solutions consists of two major types of approaches, the Ultimate MIC and Ultimate SMT. The Ultimate MIC approach is utilized when the majority of the electrical components are bare die and chip, while Ultimate SMT technology is employed when there is a prevalence of surface mount devices. Each type of technology promotes the ability to combine traditional MIC chip and wire hybrid technology with high volume, low cost, surface mount assembly techniques. As a result our modules or compact sub-systems demonstrate unrivaled and previously unachievable integration levels. The results are smaller, reduced cost, higher performance solutions that combine microwave, bias/control circuits, and DSP functions interconnected with high isolation promoting multi-layer signal routing.
Narda-MITEQ has three state-of-the-art facilities dedicated to IMA products; a 150,000 sq. ft. plant in Hauppauge, NY (design, development and production); another 20,000 sq. ft. plant in Heredia, Costa Rica (production); an 8,000 sq. ft. design center in San Diego (design and development). Narda maintains two Class 100,000 clean rooms.
Narda-MITEQ produces three types of IMA products.
Simple IMA modules integrate two or more microwave components into a functional assembly using conventional MIC technology.
Complex IMA Modules use MMC technology to create a much higher level of integration. These modules typically use the Ultimate MIC or Ultimate SMT topology.
