Fixed Waveguide Attenuator for Ka-Band

Waveguide Fixed Attenuator For Ka-Band

ATM offers a series of fixed rectangular waveguide attenuators covering the Ka-Band at 18.3 - 20.2GHz for the downlink and 27.5 - 31.0GHz for the uplink. Standard waveguide attenuation values are 3dB, 6dB, 10dB, 20dB and 30dB (other attenuation values available, consult factory for details).

Fixed waveguide attenuators are constructed with 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 call us and discuss your needs for waveguide attenuators with one of our design engineers.
