The rotating joint is mainly used for the connection of fixed part and rotating part in the radar feeder system. The product frequency range covers 2.6-40GHz.According to the structure, it can be divided into type I, L and U, etc. According to the component channel, it can be divided into single-way, double-way and multi-way rotating joint.
Flange type: Multiple types available - see Dolph Microwave Flanges page.
Finish: Corrosion protection plus black top coat.

Double-ridged rotary joints are available for all frequency bands. It has ports in U-style, L-style, or both the ports in I-style.
They are used for the rotary transmission of power and signal between the stationary and rotating parts of a radar or satcom system. Moreover, the double ridge waveguide rotating joints can transmit microwave energy from fixed lines to the rotating ones without degradation in their performance.
