Precision Fixed Attenuator

41 Series

Anritsu attenuators define the standard for fixed attenuator performance and reliability with the 41 series gold line. The Gold Line models are available for applications in metrology and calibration laboratories where precise characterization is essential. Each is provided with attenuation and SWR calibration data. Calibration data is also optionally available for individual units, each of which is serialized. Adding Gold Line attenuators to your attenuation measurement setup will improve your measurement accuracy.

The 41 Series has offerings based on the user’s desired frequency range. The 41KB series has frequency coverage up to 26.5 GHz and has a K connector® that is compatible with 3.5 mm interfaces. The 41 KC series has frequency coverage from DC to 40 GHz and also features Anritsu’s patented K connector®. For higher frequency options, the 41VA series can offer coverage up to 70 GHz. For broadband millimeter coverage, the 41W series can extend frequency coverage from DC to 110 GHz using Anritsu W1 connectors® and is compatible with 1.0 mm interfaces.
