SAN-125I125I-S1 is a Ø0.125” diameter circular waveguide rotary joint that covers the frequency range of 60 to 90 GHz. The rotary joint provides consistently low insertion loss throughout its rotation. The rotary joint also incorporates high precision bearings and propriety mechanical design to ensure smooth mechanical rotation. The rotary joint is equipped with two Ø0.125” circular waveguides with UG-387/U anti-cocking flanges. The rotary joint supports circular polarized waveforms.
