26.5-40GHz WR-28 WAVEGUIDE ATTENUATOR
Select the attenuation type –
Choose a WAVEGUIDE ATTENUATOR as fixed or variable based on whether you need constant or adjustable signal reduction.
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.
Connect in series in the transmission line –
Insert a WAVEGUIDE ATTENUATOR directly between the source and the load, with appropriate flanges on both ends.
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.
Match flange types –
A WAVEGUIDE ATTENUATOR requires the same flange type (UG, CPR, cover, or choke) as the adjacent waveguide components.
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.
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.
Thermal management –
For high‑power applications, a WAVEGUIDE ATTENUATOR should be mounted with adequate heatsinking or in a location with sufficient airflow.
