Power Samplers - Waveguide Couplers

Rectangular Waveguide Power Samplers

ATM manufactures in all sizes listed below. They are an excellent and most economical way to sample RF power from the main line in a rectangular waveguide system. 

These rectangular waveguide power samplers cover the full waveguide frequency range with standard coupling values of 30db, 40db, and 50db, however other options are available.

Power samplers are offered with standard RF connectors including SMA and Type-K on some models. Manufactured in aluminum or copper/brass construction. Double ridge waveguide power samplers are also available.

Pressure sealed waveguide power samplers are also available for microwave applications that require sealed systems. Multiple flange and coaxial connector types and configurations are also available. For more information please call us to discuss your needs with our design engineers.
