A waveguide rotary joint is used in microwave communications to connect two different types of RF waveguides. Because coaxial parts are symmetrical in ø direction, free rotation without performance degradation is accomplished. In the rotating part, electrical continuity is achieved by λ/4-chokes eliminating metal contacts. The Rotary Joints can have both waveguide ports at a right angle to the rotational axis, "U-style", one waveguide port at a right angle and one in line, "L-style" or both waveguide ports in line. "I-style". Waveguide Rotary Joint modules are available for all frequency bands.
Famous quotes containing the word joint:
“Let me approach at least, and touch thy hand.
[Samson:] Not for thy life, lest fierce remembrance wake
My sudden rage to tear thee joint by joint.
At distance I forgive thee, go with that;
Bewail thy falsehood, and the pious works
It hath brought forth to make thee memorable
Among illustrious women, faithful wives:
Cherish thy hastnd widowhood with the gold
Of Matrimonial treason: so farewel.”
—John Milton (16081674)
