T
, DIODE CAPACITANCE
(C

). C
T
is measured at 1.0 MHz using a
ca-pacitance bridge (Boonton Electronics Model
75A or equivalent).
2. T
R
, TUNING RATIO
T
R
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
ad-mittance bridge at the specified frequency and
substitut-ing in the following equations:
Q=
2πfC
G
