There is no single right answer here, but the pitfalls are shared.
1. Input matching loss before the device adds directly to the noise figure.
2. The measured value depends on the reference plane; make sure you de-embed the fixture.
3. Bias network noise injection is a common and often invisible contributor.
4. Verify the measurement with a second method, such as a noise-parameter analyser or a hot-cold load.
