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 C
J 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:
