Link Microtek AMCORJD-Ku dual-channel coaxial rotary joint

The AMCORJD-Ku dual-channel coaxial device has been designed for use in the low-profile antennas that are a key element of Ku-band satellite-on-the-move (SOTM) high-data-rate communication systems. The systems are typically deployed on military or commercial mobile platforms such as vehicles or aeroplanes.

The rotary joint is equipped with right-angled coaxial connectors to minimise the vertical space required for cables. It offers high-current capability on the receive channel, which means that both the antenna’s LNB and the motors that keep the antenna locked on to the satellite can be powered via the rotary joint, eliminating the need for additional slip rings and saving space.

The transmit channel has a frequency range of 13.75 to 14.5 GHz, with a power rating of 40 W CW, a maximum VSWR of 1.4:1 and a typical insertion loss of 0.6 dB. The receive channel can handle DC to 2.15 GHz at a microwave power of up to 1 W CW, while typical VSWR and insertion loss are specified as 1.5:1 and 0.5 dB respectively. Maximum current rating for the receive channel is 2 A at 24 VDC.

The body of the device is fabricated from aluminium with an Iridite finish and measures 36 mm in diameter and 31.6 mm in height. It incorporates a 63.5 mm-diameter bulkhead flange.
