Dual-channel coax rotary joint

18 September 2013 Interconnection

New from Link Microtek is a broadband dual-channel coaxial rotary joint that employs special contacting technology to give it long life in commercial and military satellite communications applications.

The compact AMCORJD device is ideal for use in small-footprint stabilised VSAT antennas, which are commonly installed onboard maritime vessels, in vehicles and in ground-based systems to allow access to broadband communication services.

The rotary joint provides one DC – 18 GHz transmit channel featuring a maximum VSWR of 1,8:1 and a power handling capability of 200 W CW across the full frequency band, together with a second DC – 4 GHz channel for receive signals. Maximum insertion loss is 1,5 dB for channel one and 0,2 dB for channel two, and isolation between the channels is specified as 50 dB.

With a body diameter of 32 mm and an overall length of just 38 mm excluding the SMA female connectors, the AMCORJD is particularly well suited to systems where space is at a premium. Fabricated in aluminium with an Iridite finish, the rotary joint incorporates a 51 mm diameter bulkhead flange as standard and can also be supplied with an integral slip-ring ­assembly if required.
