Satellite communications components get smaller and lighter

Available from Aspen Electronics is the Diamond Antenna and Microwave's 20-22124-0. This rotary joint was developed for airborne Satcom applications requiring a low profile antenna system to minimise drag on the exterior of the aircraft.

Because of its size, it can be used in applications which depend upon light weight, small size and high performance. Material and finish selections, design mechanics and the use of precision preloaded ball bearings are said to allow this model to be used in almost any ground, sea or airborne applications.

The Diamond 20-22124-0 is therefore suitable for new applications. However, where this part is being considered to replace an older, larger waveguide rotating joint, additional waveguide feeders can be attached and matched to maintain overall RF performance and interface with the existing waveguide runs.
