At IMS t2026 in Boston, Massachusetts, Flann is showcasing a range of solutions in WG32/WR3 waveguides, including the company's industry standard programmable rotary vane attenuator, a brand-new programmable linear vane attenuator, high-power terminations and a selection of horn antennas. To connect everything, the exhibition features Flann's formable waveguide along with examples of the traditional fixed approach. To switch between the waveguide paths, two of the highest frequency waveguide switches in the world, capable of up to 330 GHz, will be demonstrated.
To compliment the tiny waveguide size of WR3, the FSM-45 flange interface is included on a selection of
Source: Flann components. At approximately half the diameter of the current 1785.2a flange it allows for greater compactness, which is especially important at these frequency ranges where path length has such an effect on performance. The FSM-45 flange is currently being considered for inclusion in the next iteration of the IEEE 1785.2 standard.
The U.K. National Physical Laboratory has verified the performance of the FSM-45, when compared with the current IEEE 1785.2a flange; the former demonstrating consistently better performance during the assessment. James Skinner from NPL will be presenting a paper at ARFTG on this subject on Friday, June 12.
Prepare for a surprise at the stand, which includes an inventive way to use Flann programmable attenuators with the Keysight VNA and VDI frequency extenders. Be sure to stop by to see the Skyline!
