MOTOROLA RF/IF DEVICE DATA
Rs can be ignored. The value for C3 and L2 are chosen so
that
Xc3 = Xl2
when C3 is adjusted to approximately half its maximum
capacitance. At this setting, the combination produces a zero
change in the overtone frequency. If C3 is then chosen so
that Xc3 at minimum capacitance is
[Xc3(max)] – Xl2 >=
Ff (ppm) Z(crystal)
and L2 is approximately
Xc3(max)
XI2 =
2
then
Xc3(max) >= 2[
Ff (ppm)] Z(crystal)
and
Xc(max)
4
Xc(min)=
This results in an adjustable change in the operating
frequency of +[
Ff (ppm)] and –[
Ff (ppm)]/2. If ratios nearer
to 1:1 are used for Xc3(max) and Xl2, the tuning range will be
skewed with a wider –[
Ff (ppm)] but at the expense of less
adjustability over the +[
Ff (ppm)] range.
