Selection of the Temperature Coefficient Code (N Value)

1. Select sample of 5 units from the lot. Measure and record the attenuation
from DC~6 GHz every 20℃ over the temperature range -55℃~+150℃
2. Calculate, using linear regression, the slope of curve.
3. Calculate temperature coefficient code using the following formula:
Temperature Coefficient Code(N value) = Slope/Attenuation@25℃
4. Notes: For example 4N9, when temperature changes by 1℃, the attenuation
variation equals 4 dB ×0.009(temperature coefficient code) ×1℃=0.036 dB.
When temperature changes by 100℃, the attenuation variation equals
4 dB × 0.009 × 100 ℃ = 3.6 dB.
