Waveguide Circulators



Microwave Techniques manufactures waveguide circulators with industry-leading features for high-power RF and microwave applications. Our designs offer the highest peak and average power level handling in the industry. These units are available in several standard waveguide sizes.

Devices are available in 3-port and 4-port configurations from WR90 to WR2300+.

Our circulators exhibit extremely minimal insertion loss, while maintaining extremely high isolation.

In addition to our standard product offering, we also offer new waveguide circulator design and development programs for all custom solutions and applications.

    Our design capabilities for waveguide circulators continue to expand. Current capabilities include:
  • A rapidly growing line of ISM band solutions
  • Standard and custom solutions for UHF, L, S, C, and X Band.
  • New control technology adaptations, including CCS with updated software
  • Development of the most advanced devices for high-energy physics applications
  • Experience developing units to protect magnetrons, klystrons, TWTs, SSPAs, and more
If you do not see the specific waveguide circulator you require, contact sales@microwavetech.com to discuss your exact product requirements with a technical sales engineer.
