Knob Variable Attenuator

Professional Knob-Operated Variable Attenuators | SMA, N-Type, 4.3-10 Female

Our Precision Rotary Step Attenuators provide engineers with a tactile, high-accuracy solution for manual signal leveling and path loss simulation. Designed for both laboratory R&D and field infrastructure testing, these knob-operated units offer seamless attenuation control across the DC to 6 GHz spectrum.

Whether you require ultra-fine 0.1 dB resolution for metrology or massive 120 dB isolation for receiver sensitivity testing, our variable attenuators deliver repeatable performance with a "Native Interface" advantage.

Key Performance Categories:

• Ultra-Fine Resolution (0–1dB Range): Featuring 0.1 dB steps, this model is the industry standard for precision signal leveling, allowing for microscopic adjustments in high-stakes calibration environments.
• Standard Lab Ranges (0–11 dB & 0–70 dB): Perfect for general-purpose testing, IoT device characterization, and signal fading simulation.
• High Dynamic Range (0–100 dB, 110 dB, & 120 dB): Engineered for extreme isolation. These high-range units allow you to drive signals down to the noise floor to find the absolute "break point" of high-sensitivity receivers in 5G and Aerospace applications.
