| HengDa Microwave offers a series of rectangular waveguide attenuators. Typical Attenuation values are 3dB, 6dB, 10dB, 20dB and 30dB (other attenuation values available, consult sales engineers for details). The assembly construction includes a precision element for optimum electrical performance, but note that Attenuation vs. Frequency can vary greatly depending on the attenuation at a given frequency. Waveguide Fixed Attenuators with normal and high power units are also available. For more information feel free to call us and discuss your needs with one of our sales engineers. |

* The Standard Model Numbers above are the most common parts ordered for size, material and flange. However, these models can easily be altered to accommodate your needs by using the Model # code system below for complete part number.
** Please refer to the Technical Reference section for flange types/connectors details. Please contact us for your specific requirements.
*** Nominal Attenuation Accuracy: + 0.5dB, Frequency Sensitivity: + 0.7dB. Customer must choose the attenuation value appropriate for application (3dB, 6dB, 10dB, 20dB, 30dB) and insert it in the part number where Attenuation value is listed.
