Notes:
2. Quality Factor is measured on a sample of 10 Beam Lead devices selected at random from the production wafer and assembled in a ceramic
microstrip package. The measurement is carried out at a test frequency above 1 GHz and extrapolated to 50 MHz.
3. Total Capacitance Ratio is measured on the sample of 10 devices used for Q measurement.
4. Measurement/Calculation of Capacitance-Voltage Slope Exponent (Gamma).
The capacitances of a sample of 10 diodes taken at random from the production lot are measured at 2.0, 3.0, 4.0, 6.0, 8.0, 9.0, 10.0, 12.0, volts
reverse bias voltage. Junction capacitance CJ is calculated by subtracting the package capacitance of the test package. The Gamma values are
then calculated between each pair of adjacent voltages using the following formula:
log10 {Cj (VR1) / Cj (VR2) }
γ = log10 {VR2 + 1.3 / VR1 + 1.3}
