QV Band Waveguide Rotary Joint
Rotary JointsQV-band
Overview
The QV Band Waveguide Rotary Joint (JL5.974.0001) is a dual-channel device developed for spaceborne QV-band feed antenna systems, enabling efficient and stable microwave signal transmission while rotating. Operating across 37–50 GHz with BJ400 (WR22) waveguide ports, it achieves insertion loss ≤0.3 dB, VSWR ≤1.25, and VSWR variation ≤0.05. At just 60 g, it is optimized for weight-critical satellite payload applications including antenna pointing mechanisms and solar array drive systems.
