Rotary JointsSource: Cobham
A rotary joint is the key component of any rotational radar system. It is an electro-mechanical device that provides the critical interface between the stationary and rotating sections of a radar system; allowing signals to be transmitted back and forth between the antenna and ground components with little or no distortion.
Microwave Components - Methuen is the leading designer and manufacturer of microwave rotary joints in the world with over 40 years experience in the industry. With the acquisition of the Mast, Premier and Airtron rotary joint product lines, Microwave Components - Methuen now has an active rotary joint design data base that exceeds 3500 models. Microwave Components - Methuen's rotary joints cover a myriad of applications that range from submarine periscope and shipboard avionics to ground-based, vehicle-mounted, air traffic control, airborne and space-based systems. Kevlin is the prime supplier and repair source of rotary joints to the US ATC market.
A rotary joint is a passive rotating transmission line that has the ability to pass D.C. and R.F. signals with minimal degradation. It can be as simple as 1 channel (1 inch long) or as complicated as 73 channels (16 feet long).
They are true electro-mechanical devices in which the mechanical design considerations are equally as important as the R.F. design considerations. Other devices, such as slip rings (low frequency and power rotating joints), optical encoders (angular position measuring devices), gears, motors, etc. can be integrated into the Rotary Joint assembly.
