Link Microtek will be using this year’s European Microwave event to highlight 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 operations in the UKJ, the compact AMCORJD device is intended 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-18GHz transmit channel featuring a maximum VSWR of 1.8:1 and a power handling capability of 200W CW across the full frequency band, together with a second DC-4GHz channel for receive signals. Maximum insertion loss is 1.5dB for channel one and 0.2dB for channel two, and isolation between the channels is specified as 50dB.
With a body diameter of 32mm 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 51mm-diameter bulkhead flange as standard and can also be supplied with an integral slip-ring assembly if required.
