Precision RF Variable & Step Attenuators for Lab Test, ATE, and Wireless Infrastructure
Engineered for rigorous laboratory testing, automated test equipment (ATE), and telecommunication system calibration, our comprehensive series of RF Variable Attenuators and manual step attenuators delivers precise, repeatable signal level control from DC up to 6 GHz. Available in frequency tiers covering 1 GHz, 3 GHz, 4 GHz, and 6 GHz, these robust mechanical attenuators offer flexible interface options including SMA, N-type, and 4.3-10 connectors.
Whether you require ultra-fine resolution for delicate receiver calibration or wide-range attenuation for high-power signal reduction, our portfolio supports diverse step configurations and total attenuation ranges: 0–1 dB (with 0.1 dB ultra-fine steps), 0–10 dB, 0–30 dB, 0–60 dB, 0–70 dB, 0–90 dB, 0–100 dB, and 0–110 dB. Utilizing precision rotary or toggle switching mechanisms with low-loss resistive networks, every unit ensures exceptional phase stability, low insertion loss, and high attenuation accuracy across broadband operating frequencies.
