Dolph Microwave’s waveguide rotary joint available styles defines by physical geometry as follows: U, L, I or F configuration, and WR-284 to WR-28 waveguide sizes. In short, Rotary Joints (rotary couplers) applies to transmit microwave energy from stationary lines to rotating lines. Also, We designs and manufactures single channel, multi-channel waveguide and/or coaxial rotary joints (rotary couplers), with various channel configurations, as well as interface standards and designs, and that suit customer’s mechanical constraints and RF requirements.
