Adjustable Attenuator
ACST 536x Adjustable Attenuators are precision-engineered waveguide components that provide accurate, repeatable control of signal power from 50 GHz to 500 GHz. Designed for laboratory and measurement systems, these passive attenuators ensure minimal reflection and stable attenuation performance across the full frequency band. Each model features a robust gold-plated brass and aluminum body with fine mechanical adjustment for consistent attenuation and low insertion loss. Typical attenuation values reach up to 25 dB, with flat response and high repeatability for demanding millimeter-wave setups. These units are ideal for test benches, calibration, and power leveling applications across WR-15 to WR-2.2 waveguide sizes. Custom attenuation ranges and mechanical configurations are available upon request.
