Pasternack, a provider of RF, microwave and millimetre wave products, expands their waveguide product portfolio with the addition of new flexible waveguides that operate up to 40GHz over nine frequency bands. This offering consists of 36 models of flexible waveguide twists ranging in size from WR-137 (as low as 5.85GHz) to WR-28 (up to 40GHz).
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 0.07 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 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 an ideal solution for test labs or prototyping, these flexible waveguides can easily be flexed and twisted to conform to various misalignments in waveguide systems. These flexible waveguide twists can be ordered in standard lengths including 12, 24 and 36 inches with same-day shipping.
