Double Ridge Waveguide RF Power Samplers

Double Ridge Waveguide Power Samplers

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

These double ridge 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 construction. Rectangular waveguide power samplers are also available.

Pressure sealed double ridge waveguide power samplers are also available for rf 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.
