Microwave Development Labs (MDL) has introduced a pair of new WR90 waveguide rotary joints in “U” and “F” configurations.
In the F-type rotary joint, one inline arm is fixed to the housing and the other arm is free to rotate. In the U-type rotary joint, both waveguide ports are at a right angle to the rotational axis. The broadband rotary joints provide full frequency coverage from 8.0 to 12.4 GHz with loss insertion loss and low VSWR.
The maximum insertion loss across the band and insertion loss due to rotational effects (WOW) is 0.3 dB. The maximum VSWR from 8.0 to 8.5 GHz is 1.35:1, with maximum VSWR of only 1.20:1 across the remainder of the frequency range, from 8.5 to 12.4 GHz. The maximum VSWR due to rotational effects (WOW) is only 1.05:1.
The rugged WR 90 waveguide rotary joint is constructed with high-grade aluminum with a light-weight, corrosion-resistant iridite finish.
