Verify the finished assembly's resistance, RF match and thermal arrangement before applying full rated stress. Use a controlled progression within documented limits.
How it works in practice
Begin with power removed for mechanical and electrical checks. Perform low-power RF measurements with appropriate calibration. Then increase operational stress gradually while monitoring the specified temperatures. The test needs defined acceptance limits; avoid claiming qualification from a brief observation alone.
Example and interpretation
A load assembly that passes low-power S11 still needs its thermal behavior checked under representative sustained power.
Checks before use
- Inspect assembly
- Check DC behavior where appropriate
- Measure RF match
- Verify thermal operation
Important limit
A successful low-power sweep does not establish full-power durability.
