MMW waveguide attenuators are continuously variable

Pasternack has introduced a new family of in-stock continuously variable waveguide attenuators with performance up to 110 GHz. These millimeter wave waveguide attenuators are commonly used in the aerospace, defense, industrial, telecom, instrumentation and medical industries for applications such as high efficiency RF/microwave transmissions, test benches, SATCOM, MILCOM and radar testing.

The new continuously variable waveguide attenuators from Pasternack are offered in 5 unique models covering a broad frequency range of 33 GHz to 110 GHz in five bands. Engineers often use this type variable attenuator when they are designing a system and are testing their design concepts in the lab. These ultra-high frequency variable waveguide attenuators allow the designer to see how the system will perform at various signal strengths and can also be used to determine the optimum signal performance of the system.

Pasternack’s continuously variable waveguide attenuators can vary the attenuation level from 0 to 30 dB over the specified band allowing the user to dial in the attenuation level needed for the application. Another valuable feature of these waveguide attenuators is that the attenuation level is adjusted using a micrometer, enabling repeatable and rapid re-setting to different attenuation levels. These attenuators also boast flat performance across a wide band low insertion loss.
“With addition of these new in-stock continuously variable waveguide attenuators, Pasternack continues its strategic objective of providing customers around the globe access to hard-to-find RF, microwave and millimeter wave components available for same-day shipping,” explains Mark Blackwood, Passive Components Product Manager at Pasternack. “With lead times that commonly exceed 8 to 12 weeks in this industry, Pasternack now offers a comprehensive portfolio of innovative waveguide components from stock.”
