Flexible Waveguide Product Line expanded

We expanded our flexible waveguides product portfolio with the addition of new products that operate up to 40 GHz 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).
These Pasternack twistable flexible waveguides, also referred to as a “flexguide”, utilize helically wound silver coated brass strips surrounded by a flexible and twistable, yet durable, neoprene sleeve. The ends of the flexible waveguide are terminated with brass flanges available in nine waveguide sizes and multiple flange styles. Typical VSWR for these waveguides that are flexible 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 0.07 dB. 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 new Pasternack flexible waveguide sections from Pasternack act as a malleable conduit in systems where there is not perfect alignment for a traditional rigid section. Often an ideal solution for test labs or prototyping, these flexible waveguides can easily be flexed and twisted to conform to various misalignments in systems. These flexible waveguide twists can be ordered in standard lengths including 12, 24 and 36 inches with same-day shipping.
