Fixed Precision Waveguide Attenuators For Ka-Band

Ka-Band Fixed Precision RF Attenuators

Narda-MITEQ manufactures a complete series of High-Power and Low-Power precision attenuators covering the Ka-Band download frequency in WR51 and WR42 and upload frequency in WR34 and WR28 on attenuation values of 10dB, 20dB, 30dB, 40dB and 50dB.

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. For more information feel free to call us and discuss your needs for precision waveguide attenuators with one of our design engineers.
