MICROWAVE DEVELOPMENT LABORATORIES
The World Leader in Waveguide Components

About

Established in 1948, MDL is the largest independent producer of waveguide and subassemblies in the microwave industry. The company is headquartered in Needham, Mass.

MDL’s product lines include waveguide bends and twists, directional couplers and monopulse comparators, rotary joints, microwave filters, rotary switches and waveguide shutters, waveguide pressure windows and other components. Besides manufacturing thousands of standard microwave components, our engineers, who are experts in various areas of the technology, are accustomed to cooperating with our customers who have special electrical and mechanical requirements. In fact, such specials are routine at MDL .

It has always been a policy to equip the company with a wide range of superior equipment. Our engineers use computers and exclusive MDL programs to produce our accurate electrical designs quickly. MDL machinists have computer-assisted machines at their disposal as well as screw machines and other specialized quality production equipment. The fabrication group uses the MDL foundry, dip brazing shop, and paint shop. All of these result in better control over the production cycle and quality of our products.

High reliability is MDL’s trademark. This concept is embodied in the “Quality Manual” and ” Quality Procedures” using ISO 9001-2000. Calibration of electrical and mechanical equipment takes place in-house using written procedures per ANSI/Z540.

Great selection, service, quality and prices keep our customers coming back.

  • Total Control for Total Perfection

    Total Control for Total Perfection. Great ideas, great solutions, come from great engineering minds, and we have some of the best in the industry. By providing our engineers with state of the art manufacturing and testing facilities under the same roof, they can watch their designs come to life and control every aspect of their project’s development to perfection. And you, as a customer, are welcome to collaborate with them every step of the way.
  • Engineering Capabilities

    Engineering Capabilities. Meeting today’s design challenges not only requires expertise, but top shelf hardware and software as well. It has been our policy since our founding to equip our engineers and machinists with the finest tools available. Aside from employing proprietary MDL software, our computerized design systems also utilize Solid Works and Ansoft HFSS capabilities. Using Solid Works we first design a 3D model then Ansoft HFSS computes s-parameters and full wave fields, analyzes port impedances, complex propagation constants, electromagnetic fields, and radiated electric fields for open boundary problems, exporting the data for use in linear and non-linear circuit simulations. The beauty of the Ansoft system lies not only in its functionality, but in its speed, allowing us to turn your design challenges into real solutions quickly.
  • Quality Manufacturing Capabilities

    Quality Manufacturing Capabilities. MDL’s in-house manufacturing facility encompasses CNC machining centers, aluminum dip brazing, EDM facilities, cleaning, impregnation, iridite, heat treating, RF testing, and finishing. Off the shelf items, as well as custom pieces that require special tolerances, complicated configurations, multiple formed bends, twists, or offsets are manufactured with precision, and are subjected to complete inspection and testing.
  • Reliability guaranteed

    Reliability guaranteed. All MDL products undergo 100% functional performance verification as required per ISO 9000. Fully automated, software controlled and networked RF test stations are used throughout our facility. Our test capabilities (DC to 40GHz) encompass VSWR, loss, attenuation, delay, and phase matching. Data collection and product traceability are available to support your needs, and performance criteria are always tailored to meet your most stringent requirements.
  • In Partnership with our Customers

    In Partnership with our Customers. Over a span of more than 50 years, MDL has honed itself into a company driven by its customers’ needs. From a single custom piece to off-the-shelf items, to mass production runs, we are here to work with you to provide the expertise and quality assurance your project deserves, at a very competitive price.

  • A History of Tomorrows

    A History of Tomorrows. When we pioneered the Riblet Coupler back in 1948, we had a pretty good idea that microwave technology was the coming thing. As a result, we’ve never stopped inventing, testing, and perfecting microwave coupling solutions. During the ‘60s, we came up with the thin wall monopulse comparator for the Lunar Excursion Module. The ‘70s saw us developing waveguide feed and monopulse networks for F-14 and F-15 aircraft. As related technologies expanded, we shrank the size of our products to accommodate them. In the 1980s, we introduced internally milled technology to reduce the size and weight and improve the performance of our products for the F-18 and B-1 radar systems. We anticipated today’s demands for smaller, more precise waveguide products, such as Longbow and Milstar programs for higher frequencies, as well as shorter lead times and more cost-effective solutions.

    Tomorrow, we envision the explosion in microwave technology touching the lives of countless millions of end users around the world. Foresight has made us the world’s largest independent producer of waveguide components and subassemblies in the industry.

    We will continue to make history.
