Entering 299C GaAs FET Transistors
The following table describes the part parameters required for the GaAs FET subcategory when 299C is the selected calculation model.
Parameter
Type
Description
Foreign
Checkbox [Parts Count also]
Indicates whether the device is made in China. If this checkbox is selected, the failure rate of the part is calculated based on Appendix A for the 299C Parts Count or Parts Stress model chosen.
Two Sided
Checkbox [Parts Count also]
When selected, the device is two-sided. Data entry fields for the second side become available. The fields for side 2 apply only to side 2. The thermal resistance and minimum temperature rating values for side 2 are assumed to be the same as the values for side 1.
Quality Level
Choice List [Parts Count also]
The appropriate quality screening level of the device. Accepted quality levels and values for this subcategory follow.
A2 = 0.03
A3 = 0.05
A4 = 0.10
A5 = 0.20
B1 = 0.50
B2 = 1.00
C = 5.00
Application
Choice List
Not required when Foreign is selected.
The application of the device in the circuit. Choices are:
CW (Continuous Wave)
Low Power or Pulsed
Internal Matching
Choice List
Not required when Foreign is selected.
The internal matching of the transistor. Choices are:
Both Input and Output
Input Only or Output Only
No Matching
Average Output Power
Real (Watts)
Not required when Foreign is selected.
The average output power of the device. Refers to the power level for the overall packaged device and not to the individual components within the device.
Frequency
Real (GHz)
Not required when Foreign is selected.
The operating frequency of the device in gigahertz.
