  • Product Description
  • Main Parameters
  • Structural parameters
  • The YD-WRJ10-I is a Type I waveguide rotary joint operating in the W band, with a frequency range spanning 75 to 110 GHz.

    The rotary joint employs high-precision bearings and a non-contact mechanical design to ensure stable amplitude and phase stability during rotation.

    Furthermore, this joint features a non-contact mechanical design, thereby exhibiting high power-handling capability.
