PARAMETER TEST METHODS
1. C
T
, DIODE CAPACITANCE
(C T = C C + C J ). 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.
4.T CC,DIODE CAPACITANCE TEMPERATURE
COEFFICIENT~
~ T CC is guaranteed by comparing CT at
V R=4.0Vdc,f=1.0MHz,T A= – 65°C with CT at V R=4.0Vdc,
f=1.0MHz,T A= + 85°C in the following equation,which
defines TC C:
C T(+85°C) – C T(–65°C )
106
.
TC C =
85+65
C T(25°C)
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
