Millimetre wave guide with swivel
Link Microtek's inline millimetre-wave swivel joint has an operating bandwidth of 26.5 to 40GHz.
Link Microtek has introduced an in-line millimetre-wave swivel joint that offers a wide operating bandwidth of 26.5 to 40GHz Making use of a WR28-size aluminium waveguide, the new device's internal construction consists of a series of cascaded steps that enable the end flanges to be rotated up to 90 degrees relative to each other

Now available from Link Microtek is a new range of low-cost, plastic-packaged MMIC voltage controlled oscillators (VCOs) that feature a high level of integrated functionality.
This makes the swivel joint suitable for applications where polarisation needs to be changed, for example, when using a horn antenna in an EMC test chamber.
In field applications, the device can be used in place of flexible waveguide or as an alternative to a rotary joint on a dithering antenna.
Measuring just 50.8 (L) x 19.0 (D) mm, the new swivel joint is well matched across its full frequency band and compares favourably with 360-degree rotary joints, which are larger, more expensive and can usually only offer narrow-band performance.
As well as the new WR28 device, Link Microtek also manufactures swivel joints in WR42 waveguide for applications in the frequency range 18-26GHz and WRD180 double-ridge waveguide, which covers the whole range from 18 to 40GHz.
