• ARRA D6844-30X variable attenuator unit

The ARRA D6844-30X is part of ARRA's mid-size continuously variable coaxial attenuator series, covering a frequency range of 0.5 to 18 GHz across the product family. The D6844 series specifically covers 7.0 to 11.0 GHz. ARRA (Antenna & Randome Research Associates) has been a global innovator in designing and manufacturing coaxial and waveguide components for over 60 years, supplying commercial and military customers worldwide.

Attenuation is achieved in a non-contacting manner using ARRA's proprietary dissipative materials, providing wear-free performance and high reliability. Units operate over extremely wide temperature ranges with little change in attenuation characteristics. The standard Form 4061 package is ideal for applications where attenuation can be set, then locked and left for long periods. Panel-mount (P prefix), turns-counting (T prefix), and digital counter (D prefix) variants are also available.

The D6844-30X is a level-set model qualified for military applications. Full attenuation is achieved in less than 20 turns of the 1/4" shaft.
