Waveguide Direct Read Attenuator Series

Pasternack’s waveguide direct read attenuator series is available in WR-42 to WR-10 standards. Our direct read waveguide attenuator components operate in seven waveguide bands within the 18 GHz to 110 GHz frequency range. They boast +/- 2% typical attenuation accuracy and feature an easy-to-read drum scale and military standard UG-style flanges.

Direct read waveguide attenuator minimum attenuation range is 0 dB to 50 dB. These direct read attenuators have an insertion loss of 0.5 dB to 1 dB depending on the frequency range.


Waveguide direct read attenuators can be used in many industries including aerospace, defense, industrial, telecom, instrumentation and medical. They are built from quality construction materials and ensure consistent performance. As with the other over 40,000 RF, microwave and millimeter wave Pasternack components, these attenuators are in-stock. In addition, this direct read waveguide attenuator product line ships the same day as purchased.
