Satellite Waveguide Slip Ring Introduction

Satellite Waveguide Slip Ring

Satellite waveguide rotary joint was composed by two-channel microwave rotary joints and precision slip rings, which includes two-way microwave signal path, a number of power supply channels and signal channels, and can be integrated precision absolute encoder or precision rotary transformer. The excellent performance of the product, mainly used in radar antennas, mobile communications, moving the receiving antenna and so on. According to actual needs, products may change the number of the channels of the slip ring and its mounting dimensions; what’s more, it can integrate multiple types of signal channels to meet the different needs of different occasions.

Feature:

  • Microwave rotary joints and slip ring assembly

  • Bird frequencies up to 110 GHz, coaxial frequency up to 18 GHz (custom)

  • Integrate multiple types of signal channels

  • Stable performance, over-long lifetime

  • The main application of radar antennas, mobile communications, moving the receiving antenna, etc
