Pasternack expands its waveguide product portfolio with the addition of flexible waveguides that operate up to 40GHz over nine frequency bands. This offering consists of 36 unique models of flexible waveguide twists ranging in size from WR-137 (as low as 5.85 GHz) to WR-28 (up to 40 GHz).

Pasternack’s flexible/twistable waveguides, also referred to as a 'flexguide', utilise helically wound silver coated brass strips surrounded by a flexible and twistable, yet durable, neoprene sleeve. The ends of the waveguide are terminated with brass flanges available in nine waveguide sizes and multiple flange styles.

Typical VSWR for these flexible waveguides ranges from 1.05:1 up to 1.35:1 depending on waveguide size and frequency. Insertion loss performance is similar with typical levels as low as 0.07dB. These waveguides will flex in both the E and H planes and can also twist. Flanges in lower frequency versions are available in both UG and CPR styles.

The flexible waveguides sections from Pasternack act as a malleable conduit in waveguide systems where there is not perfect alignment for a traditional rigid waveguide section. Often a solution for test labs or prototyping, these waveguides can easily be flexed and twisted to conform to various misalignments in waveguide systems. These waveguide twists can be ordered in standard lengths including 12, 24 and 36" with same-day shipping.

“Our new family of flexible waveguide components provides designers and engineers an in-stock source of flexible/twistable waveguide solutions for their applications up to 40 GHz,” explains Mark Blackwood, Passive Components Product Manager, Pasternack. “Pasternack’s rapidly expanding ready-to-ship waveguide family is the largest in the industry and provides customers a comprehensive suite of waveguide solutions.”
