V-, E- and W-Band Rotary Joints and Flexible Dielectric Waveguides for Measurement Applications

Full-band designs for V-, E-and W-Band rotary joints—covering the frequency ranges from 50 to 75 GHz, 60 to 90 GHz and 75 to 110 GHz, respective­ly—have been added to SPINNER’s rotary joint portfolio, which initial­ly covered narrowband W-Band. The new rotary joint models have the article numbers BN 636281 (V-Band), BN 636282 (E-Band) and BN 636283 (W-Band). Data sheets are available for downloading using our Product Finder (Link).

SPINNER RotaryJointSPINNER’s aim has been to ensure outstanding insertion loss and VSWR performance across the full frequency bands of the new range of rotary joints. All three rotary joints typically have a VSWR better than 1.5 and insertion loss below 1 dB. Another main design goal was excellent stability with rotation. Over their full frequency bands, insertion loss variation with rotation is less than 0.2 dB, phase variation typically less than 2 degrees. These features make them the only rotary joints on the market that can provide this performance over their full waveguide bands.

For high-end testing applications requiring very low insertion loss, high stability and good VSWR, flexible dielectric waveguides for the E-band (BN 533659) and W-band (BN 533660) are available for supplementing the rotary joints. These come in standard lengths of 30, 60 and 90 cm and can also be easily reconfigured to custom lengths. The actual transmission line consists of a polymer plastic material. This reduces weight and results in extreme flex­ibility, very low transmission loss and high stability, offering a high-performance alternative to a tradi­tional flexible waveguide section or test cable. These devices are ideal for antenna test chambers, material testing and general measurement applications.
