The new AM28RJD dual-channel rotary joint from manufacturer Link Microtek, provides an effective means of reducing component count and saving space and weight in the compact antennas that are used for Ka-band, high-data-rate SOTM (satellite on the move) communication systems.
Particularly suitable for military or commercial airborne systems, such as satcom uplinks in unmanned aerial vehicles, the device features a high-power, low-loss WR28 waveguide transmit channel, together with a coaxial receive channel offering a high current rating of 2 A at 24 V d.c., which enables it to power the antenna’s LNB and servo motors without the need for additional slip rings.
The central transmit channel has a frequency range of 29–31 GHz, with an average power rating in excess of 50 W, typical insertion loss of just 0,5 dB and a maximum VSWR of 1,7:1. The receive channel can handle frequencies up to 3 GHz at an average microwave power of 1 W, and its typical VSWR and insertion loss are specified as 1,5:1 and 0,25 dB respectively.
This robust part is fabricated from lightweight aluminium with an Iridite finish. Right-angle waveguide bends are used on the transmit channel to save additional space, resulting in overall dimensions of just 36 mm (D) x 90,3 mm (H), with a 50 mm diameter UBR320 bulkhead flange as standard.
Other rotary-joint configurations and sizes are available on request, tailored to suit specific antenna requirements.
