Link Microtek has launched a new miniature single-channel coaxial rotary joint that provides a broad operating frequency range of DC to 40GHz, making it ideal for a variety of test applications.

Particularly, it would be excellent for EMC evaluation of 5G systems and performance assessment of antennas for radar systems at the lower-frequency end as well as Ka-band satellite communications systems at the higher end.

The AMCORJ-WB2 rotary joint is a sliding-contact design, providing inherent advantages of low insertion loss and good VSWR performance over an extensive frequency range. Maximum insertion loss for the device is defined as 1dB, while maximum VSWR is 1.8:1.

With overall dimensions of just 33.7mm (L) x 30mm (D), this small rotary joint incorporates 50Ohm impedance 2.92mm (K-type) female connectors and weighs only 43.7g. It provides a long, reliable life, and has been tested to over one million rotations at 50rpm.

The device offers a robust stainless-steel construction with a passivated finish and an operating temperature range of -20C to 70C.
