PARAMETER TEST METHODS
1. C
T
, DIODE CAPACITANCE
(C
T
= C
C
+ C
J
). C
T
is measured at 1.0 MHz using a
capacitance bridge (Boonton Electronics Model 75A or
equivalent).
2. TR, TUNING RATIO
TR is the ratio of C
T
measured at 2.0 Vdc divided by C
T
measured at 30 Vdc.
3. Q, FIGURE OF MERIT
Q is calculated by taking the G and C readings of an
admittance bridge at the specified frequency and
substituting in the following equations:
