PCB-mounting coaxial rotary joint

30 September 2009 Interconnection

Link Microtek has introduced what is believed to be the industry’s first commercially available PCB-mounting coaxial rotary joint.

Featuring a wide operating frequency range of DC to 5 GHz, the AMCORJ-PCB-SCA1 device is designed to allow a coaxial cable to be rotated through 360° while connected to a printed circuit board. It is ideally suited for coiled-cable applications in medical or satcom systems and also serves to protect both the cable and the PCB from damage whenever equipment is moved.

Manufactured from Alochromed aluminium, the rotary joint incorporates a standard female SMA-type connector and a high-quality bearing to ensure high levels of reliability. It is a rugged, compact device with a diameter of 16 mm and a height of 38 mm. The rotary joint offers minimal loss of signal strength: at 5 GHz it has a maximum insertion loss of 0,3 dB and a return loss of better than 16 dB, while at 27 MHz the insertion loss is only 0,1 dB and the return loss 25 dB.
