26.5-40GHz WR-28 WAVEGUIDE ATTENUATOR

26.5-40GHz WR-28 WAVEGUIDE ATTENUATOR

• Frequency range from 1 GHz to 110 GHz+
• Improves intermodulation distortion (IMD) performance by reducing input power to nonlinear devices
• Flat attenuation response over frequency

How to Use a WAVEGUIDE ATTENUATOR (Usage Method)

1. Select the attenuation type –
   Choose a WAVEGUIDE ATTENUATOR as fixed or variable based on whether you need constant or adjustable signal reduction.

2. Verify frequency range –
   A WAVEGUIDE ATTENUATOR must be rated for the same frequency band (e.g., WR‑28 for 26–40 GHz, WR‑90 for 8.2–12.4 GHz) as your system.

3. Connect in series in the transmission line –
   Insert a WAVEGUIDE ATTENUATOR directly between the source and the load, with appropriate flanges on both ends.

4. Observe directionality (if applicable) –
   Most WAVEGUIDE ATTENUATOR designs are symmetrical and bi‑directional; however, some high‑power versions may have a preferred direction indicated by markings.

5. Match flange types –
   A WAVEGUIDE ATTENUATOR requires the same flange type (UG, CPR, cover, or choke) as the adjacent waveguide components.

6. For variable attenuators – adjust the dial/drum –
   Rotate the calibrated dial of a WAVEGUIDE ATTENUATOR to set the desired attenuation value; read the setting from the engraved scale.

7. Power rating verification –
   Before operating a WAVEGUIDE ATTENUATOR, verify its average and peak power handling capabilities—high‑power versions require forced air or water cooling.

8. Thermal management –
   For high‑power applications, a WAVEGUIDE ATTENUATOR should be mounted with adequate heatsinking or in a location with sufficient airflow.
