Coaxial rotary joint offers wideband capability for 5G test applications

Microwave and RF component manufacturer, Link Microtek, has introduced a miniature, single-channel coaxial rotary joint with a wide operating frequency range of DC to 40GHz. According to Link Microtek, this makes the AMCORJ-WB2 particularly well suited to a variety of test applications, including EMC evaluation of 5G systems. It can also be used to assess the performance of antennae for radar systems at the lower-frequency range and Ka-band satellite communications systems.
The AMCORJ-WB2 rotary joint has a sliding-contact design, which provides the inherent advantages of low insertion loss and good VSWR performance over a wide frequency range. Maximum insertion loss is specified as 1dB, while maximum VSWR is 1.8:1.
The rotary joint has overall dimensions of 33.7 x 30.0mm and incorporates 
50-Ohm impedance 2.92mm (K-type) female connectors. It weighs only 43.7g and has been tested to over one million rotations at 50rpm.
The AMCORJ-WB2 rotary joint is designed and manufactured at Link Microtek’s premises in Basingstoke. It has a robust stainless-steel construction with a passivated finish and an operating temperature range of -20 to +70 degrees C.
