Miniature dual-channel rotary joint saves space in Ka-band

LINK MICROTEK AM28CORJD miniature dual-channel rotary joint 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 device measures 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 to 31GHz and delivers improvded 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.
