What to Include in an RF Dummy Load Purchase Request

Finned N-type RF dummy load on a laboratory bench with CentronRF watermark

Specify impedance, frequency band, matching limit, continuous and pulse power, connector interface and cooling conditions. This makes alternatives meaningfully comparable.

How it works in practice

Include installation space, mounting needs and expected ambient temperature. Ask for the current datasheet when a listing lacks derating or pulse details. If weight or dimensions matter, resolve conflicting catalog fields before procurement. Define any required acceptance measurements separately from nominal product ratings.

Example and interpretation

A request for '50 ohms, N-male, 100 W continuous at 2.4 GHz' still needs thermal conditions and allowed VSWR.

Checks before use

  • State electrical limits
  • State mechanical interfaces
  • Specify cooling and ambient conditions
  • Request missing acceptance data

Important limit

Do not treat conflicting catalog fields as verified engineering dimensions.
