Waveguide Tunable Attenuator
A waveguide variable attenuator is a passive, precision device that enables continuous, dynamic adjustment of signal power. By incorporating an internal tunable absorptive mechanism or a precision displacement structure, it achieves smooth, stepless attenuation control, allowing flexible adaptation of link‑level power to meet real‑world operating conditions. Designed with a standard waveguide architecture, the device supports stable transmission of the TE10 dominant mode and offers high tuning accuracy and minimal signal distortion. It can precisely perform functions such as system power calibration, impedance matching, loop noise reduction, and dynamic range optimization, making it a core component in RF test and calibration, system debugging, and precision power‑control applications.
• Operating frequency range: 40 GHz to 220 GHz
• Multi-waveguide port WR5/WR6/8/10/12/15/19
• Low insertion loss
• Wide dynamic range: 0–60 dB, adjustment resolution of 0.1 dB
