The highlight of the Link Microtek stand at EuMW 2013 will be a new broadband dual-channel coaxial rotary joint that employs special contacting technology to give it long life in commercial and military satellite communications applications.

Designed and manufactured at Link Microtek’s premises in the centre of Basingstoke, the compact AMCORJD device is ideal for use in small-footprint stabilised VSAT antennas, which are commonly installed on board maritime vessels, in vehicles and in ground-based systems to allow access to broadband communication services.

The rotary joint provides one DC to 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 to 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 38mm 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.
