Miniature Dual-Channel Rotary Joint Saves Space In Satellite Systems

News

Link Microtek has introduced a new miniature dual-channel rotary joint that has been specifically designed to save space in antennas for Ka-band satellite-on-the-move communications systems, which are now being deployed for high-data-rate applications in both the military and commercial sectors.

With its high-power transmit channel implemented in a right-angle WR28 waveguide on the fixed (input) side and a female K-type coaxial connector on the rotating (output) side, the AM28CORJD rotary joint measures just 31.75mm (D) x 74.68mm (H), excluding the 50mm-diameter UBR320 standard bulkhead flange.

The central transmit channel covers Ka-band frequencies from 29-31GHz and delivers excellent microwave performance, with a maximum power rating of 40W CW, a typical insertion loss of only 0.6dB and a maximum VSWR of 1.25:1.

The L-band receive channel operates over the frequency range DC to 2.15GHz.
