Rotary Joint Technology

    From sophisticated medical applications which require extremely low insertion loss performance, to high speed military applications such as Airborne, ATC, Shipboard and Ground-based Radar, Spectrum Microwave’s engineers develop Rotary Joint solutions that test the limitations of today’s technology. Using a number of proprietary techniques like these, Spectrum Microwave Rotary Joint technology continues to push the bar in the industry.

  • Carbon infused electroless nickel for low insertion loss
  • Centerless ground 304 stainless steel bearings to reduce unwanted friction
  • Low spurious outputs
  • DuPont Teflon brushes for the highest degree of durability
  • Self contained pressurized bearing cases for harsh environments

Large Selection of Designs

Spectrum Microwave offers a wide range of styles and designs for today’s Rotary Joint market. From wideband DC-18 GHz high power, in-line designs to miniature 10 kilowatt models, Spectrum Microwave offers the right model Rotary Joint for your application. With over 40 years of experience and hundreds of custom designs to their credit, they continue to offer solutions that not only meet customers’ requirements, but exceed their expectations.

Custom Solutions

Custom Solutions is the cornerstone of Spectrum Microwave’s Rotary Joint business. Offering solutions that other firms choose not to bid is what separates Spectrum Microwave from other Rotary Joints companies. An example of this commitment to engineering excellence is this extremely sophisticated 7 channel space application design. Other vendors choose to pass on this request, not Spectrum Microwave. Combining sophisticated software to maintain tight tolerances and skillful assembly techniques confirms why Spectrum Microwave is a leader in sophisticated Rotary Joint designs.

Full Service Production

Spectrum Microwave applies the principles of it’s own Quality Management System to deliver the world class quality and consistency our military and commercial Rotary Joint customers demand. We carefully monitor critical phases of the production process with data logging technology and utilize our in-house testing capabilities from design through full production. The end result is a quality system worthy of our ISO9001:2000
