The WRJ-15 from Millitech is a Waveguide Rotary Joint that operates from 50 to 75 GHz. It has an insertion loss of 1 dB and can handle 350 Watts of power with an VSWR of 1.5:1. This Waveguide Rotary Joint allows the transmission of RF signals from stationary to a 360 rotating rectangular waveguide, making it ideal for mechanically scanned antennas, automatic test systems and axial ratio measurement.
The input and output ports are available in straight to straight, right angle to straight, straight to right angle, and right angle to right angle variations. There is also an extended straight port available on the flange end, as well as a circular waveguide design.
