Fixed Attenuators

Mi-Wave’s 521 Series & 524 High Power Series Fixed Attenuators are available in attenuation values up to 30 dB for each waveguide band from 8 to 220 GHz. Each fixed attenuator is calibrated at the exact frequency specified and is accurate within 0.1 dB or 1%. See desired frequencies for more information and models.

Applications
The 521 Series Fixed Attenuators are used in millimeter wave applications that require accurate fixed attenuation levels in waveguide transmission lines. All units are H-plane fixed attenuators. The attenuators are useful for isolating generators from mismatched load effects. They are also used for extending the frequency ranges of power measuring equipment and for accurately reducing signal source output levels.

What are fixed attenuators?

Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. In measuring signals, attenuator pads or adapters are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it. Attenuators are also used to ‘match’ impedance by lowering apparent SWR (Standing Wave Ratio).
